Abstract:
As a
key component of the beam
splitting and combining in photonic integrated circuits, an optical power splitter requires the characteristics of compactness, broadband,
and low loss. Here, we propose a 1 × 2 ultra-broadband 3 dB power
splitter with a 5 µm long beam splitting area, based on the structure of a subwavelength grating. The 0.45 dB bandwidth of
the TE mode achieves 790 nm from 1.25 to 2.04 µm. This power splitter has a large fabrication tolerance, exceeding more than
30 nm ( ± 15 n m ) and obtains the desired power ratio.
It is suitable for high-speed and large-capacity communication, wavelength division multiplexing systems, and other multi-wave
interconnection applications.
