Scalable single-microring hybrid III-V/Si lasers for emerging narrow-linewidth applications
arxiv(2024)
摘要
Silicon photonics, compatible with large-scale silicon manufacturing, is a
disruptive photonic platform that has indicated significant implications in
industry and research areas (e.g., quantum, neuromorphic computing, LiDAR).
Cutting-edge applications such as high-capacity coherent optical communication
and heterodyne LiDAR have escalated the demand for integrated narrow-linewidth
laser sources. To that effect, this work seeks to address this requirement
through the development of a high-performance hybrid III-V/silicon laser. The
developed integrated laser, utilizes a single microring resonator (MRR),
demonstrating single-mode operation with a side mode suppression ratio (SMSR)
exceeding 40 dB, with laser output power as high as 16.4 mW. Moving away from
current hybrid/heterogeneous laser architectures that necessitate multiple
complex control, the developed laser architecture requires only two control
parameters. Importantly, this serves to streamline industrial adoption by
reducing the complexity involved in characterizing these lasers, at-scale.
Through the succinct structure and control framework, a narrow laser linewidth
of 2.79 kHz and low relative intensity noise (RIN) of -135 dB/Hz are achieved.
Furthermore, optical data transmission at 12.5 Gb/s is demonstrated where a
signal-to-noise ratio (SNR) of 10 dB is measured.
