Si/III-V hybrid external-cavity laser stabilization using real-time micro-ring monitoring and feedback control
Jin-Hyoung Lee,Daniel Y. Lee,Jock Bovington,Ivan Shubin,Shiyun Lin,Jin Yao,Ying Luo,Stevan S. Djordjevic,John E. Cunningham,Kannan Raj,Ashok V. Krishnamoorthy,Xuezhe Zheng +11 more
TL;DR: Stable mode-hop-free operation for a Si/III-V hybrid external-cavity laser was demonstrated during 320mA bias current sweep using a real-time ring monitoring, a fast feedback control loop, and a simple bang-bang control algorithm.
Journal ArticleDOI
CW Emission and Self-Pulsing in a III-V/SiN Hybrid Laser With Narrow Band Mirror
Cristina Rimoldi,Lorenzo Columbo,Jock Bovington,Sebastian Romero-García,Mariangela Gioannini +4 more
TL;DR: In this paper , the external cavity III-V/SiN hybrid laser operates in regimes of ultra-damped relaxation oscillations or in CW unstable dynamical regimes (self-pulsing or approaching turbulence) as a consequence of mirror dispersion, non-zero linewidth enhancement factor, and four-wave mixing in the gain medium.
Patent
Thermally compensating spot-size converter for an athermal laser
TL;DR: In this article, a reflective gain medium (RGM) consisting of an optical gain material coupled with an associated reflector is coupled to a spot-size converter (SSC), which optically couples the RGM to an optical reflector through a silicon waveguide.
Patent
Single-pass ring-modulated laser
TL;DR: In this article, an optical source may include an optical gain chip that provides an optical signal and that is optically coupled to an SOI chip, which includes: a first optical waveguide, a first ring resonator, an amplitude modulator, and an output port.
Patent
Removable optical tap for in-process characterization
TL;DR: In this paper, an integrated circuit includes optical waveguides defined in a semiconductor layer, and uses removable optical taps to allow for in-process characterization and trimming, which may modify indexes of refraction of portions of the optical waveguide or may involve a more invasive process.
