Title: Charles Chih-Chin Lin and Comb Laser Innovation.

Introduction

Charles Chih-Chin Lin is an inventor based in Kanata, Canada, whose work includes an optoelectronic device designed for generating selected laser wavelengths. He is associated with Marvell Asia Pte. Ltd. His listed patent portfolio includes 1 patent.

Latest Patents

Lin’s patent, “Comb laser,” describes an optoelectronic device built around a reflective semiconductor optical amplifier (RSOA). The RSOA contains a gain medium that amplifies laser radiation within a specified gain band, a reflector at one end, and a waveguide that carries radiation into and out of the other end.

The device also includes an external laser cavity optically coupled to the waveguide and arranged on an optical substrate. Within the cavity, a comb filter passes distinct wavelength sub-bands, while a bandpass filter in series with the comb filter selects a subset of those sub-bands. Together, these components provide a way to shape the wavelengths supported by the laser cavity.

Career Highlights

The available information identifies Lin’s work through his patent on comb-laser technology and his association with Marvell Asia Pte. Ltd. The invention combines semiconductor optical amplification with filtering in an external laser cavity.

Collaborations

Xiaoguang He and Samira Karimelahi are listed as Lin’s coworkers. The available details do not specify their roles in the patent or the nature of their collaboration.

Conclusion

Charles Chih-Chin Lin’s “Comb laser” patent describes an optical device that combines an RSOA, an external cavity, and wavelength-selective filters to control laser output.
