    “Möbius” microring resonator

    Abstract: A category of optical microring resonator, which is analogous to the Möbius strip, is proposed. The “Möbius” microring resonator allows the conversion between modes with different polarizations in the ring, and light must circulate two cycles to be converted back to the original polarization status, which is similar to a Möbius strip. This topology structure of polarization makes the free spectral range half of that which corresponds to the cavity round trip. The eigenmodes of this microring are hybridizations of different polarizations, and the breaking of the rotation invariance of the ring makes the transmission related to the polarization of input light and the relative rotation of the cavity. Our work opens the door towards the photonic devices with nontrivial mode topology and provides another way to engineer photonic structures for fundamental studies.

    In-line high efficient fiber polarizer based on surface plasmon

    Abstract: An in-line high efficient polarizer, composed of tapered fiber on the Au thin film, is theoretically proposed and experimentally demonstrated. The protocol is based on the high efficient adiabatic conversion of transverse magnetic mode from tapered fiber into surface plasmon (SP) and attenuates quickly in metal film. On the contrary, the transverse electric polarized light is influenced hardly in the whole process. The polarization extinction ratio higher than 500:1 (≈27 dB) is obtained in our experiment. Our demonstration offers a potential way to manipulate the polarization of light in integrated circuit and may inspirit more attention to surface plasmon based devices for polarization controlling.

    Deterministic generation and switching of dissipative Kerr soliton in a thermally controlled micro-resonator

    In: AIP Advances, AIP Publishing, Vol. 9, No. 2 ( 2019-02-01)
    Abstract: In this paper, we first experimentally demonstrate deterministic generation and switching of dissipative Kerr solitons (DKSs) in a thermally controlled micro-ring resonator based on high-index doped silica glass platform. In our scheme, an auxiliary laser is introduced to timely balance the intra-cavity heat fluctuation. By decreasing the operation temperature through a thermo-electric cooler, primary-, chaotic-comb and soliton crystal are firstly generated, then increasing the temperature, DKSs switching and single soliton are robustly accessed, which is independent of the tuning speed. During the switching process, varieties of DKSs are identified by tens of the characteristic “soliton-steps”. Besides, by simply changing the operation temperature under which the DKSs are formed, the center wavelength of dispersive waves could be tuned in a broadband range. When the micro-ring resonator operating at temperature larger than 63.5 °C, avoided mode-crossing free soliton can be obtained. Our results are favorable for study of on-chip soliton dynamics and practical nonlinear applications.

    Opto-fluidic-plasmonic liquid-metal core microcavity

    Abstract: A hybrid microcavity based on the liquid-metal-filled silica microbubble is experimentally demonstrated, which supports both plasmonic and optical whispering gallery modes. The high quality (Q)-factor plasmonic mode of liquid metal is demonstrated via controlling the polarization of the probe laser as well as changing the liquids in the microbubble. Additionally, we reveal an unconventional Q-factor enhancement effect in the bottle microresonator. The liquid metal (mercury) could dissolve various metals and solids, meriting the optofluidic type of sensing. Combining the two kinds of high-Q resonances in the hybrid microcavity, we could probe the optical, mechanical, and thermal properties of solvents in liquid metal, providing a unique experimental platform for realizing multi-parameter optical sensing and making the detection and identification of metal and alloy possible.

    High-frequency traveling-wave phononic cavity with sub-micron wavelength

    Abstract: Thin-film gallium nitride (GaN) is a promising platform for phononic integrated circuits that hold great potential for scalable information processing processors. Here, an unsuspended traveling phononic resonator based on a high-acoustic-index-contrast mechanism is realized in GaN-on-Sapphire with a frequency up to 5 GHz, which matches the typical superconducting qubit frequency. A sixfold increment in quality factor is found when temperature decreases from room temperature (Q = 5000) to 7 K (Q = 30 000), and thus, a frequency-quality factor product of 1.5×1014 is obtained. Higher quality factors should be available when the fabrication process is further optimized. Our system shows great potential in hybrid quantum devices via the so-called circuit quantum acoustodynamics.

    Thermal bistability of magnon in yttrium iron garnet microspheres

    Abstract: In this work, the thermal bistability of magnons in yttrium iron garnet microspheres was experimentally characterized. Using high quality factor optical whispering gallery modes in the microsphere, the temperature change caused by the microwave pump is precisely measured by probing the optical resonance wavelength shift. It is found that temperature change also induces the magnonic frequency shift and the frequency shift depends on the crystal axis direction of the material. With some appropriate alignment of the magnetic field and the microsphere, the magnonic frequency shift induced by the thermal bistability from the microwave can be suppressed. Our results show its potential use in future experiments on magnon-based transducers.

    Highly efficient electrochemiluminescence from Ru(II) complex with PEO-PHP-PEO as a buffer layer

    Abstract: A blended layer composed of a coil-rod-coil triblock oligomer and LiCF3SO3 was introduced into light-emitting electrochemical cells. The response rate and efficiency of the device were greatly improved, and a low operating voltage was maintained. The device, with a structure of indium tin oxide/PEO-PHP-PEO(LiCF3SO3)/[Ru(bpy)3] (PF6)2/Au, showed a turn-on voltage as low as 2.85 V, while its luminance and efficiency were approximately twice those of a single-layer device. The power, luminance, and external quantum efficiency at 1000 cd/m2 reach 2.1 cd/A, 1.5l m/W, and 2.6%, respectively. We attribute these improvements to the enhancement in the hole injection and electron blocking effect resulting from the blended layer.
