Injection Molding of Encapsulated Diffractive Optical Elements
Micromachines, 2023 Microstructuring techniques, such as laser direct writing, enable the integration of microstructures into conventional polymer lens systems and may be used to generate advanced functionality. Hybrid polymer lenses combining multiple functions such as diffraction and refraction in a single component become possible.

Optically injected quantum-dot lasers
Optics Letters, 2010 The response of an optically injected quantum-dot semiconductor laser (SL) is studied both experimentally and theoretically. In particular, the nature of the locking boundaries is investigated, revealing features more commonly associated with Class A lasers rather than conventional Class B SLs.

Processing-Speed Enhancement in a Delay-Laser-Based Reservoir Computer by Optical Injection
Photonics, 2022 A delay-laser-based reservoir computer (RC) usually has its processing speed limited by the transient response of laser dynamics. Here, we study a simple all-optical approach to enhancing the processing speed by introducing optical injection to the ...

Robust Optical Frequency Comb Generation by Using a Three-Stage Optical Nonlinear Dynamic
Frontiers in Physics, 2021 In this article, we propose and investigate a novel scheme to generate optical frequency combs (OFCs) by using a three-stage generator, which is based on optical injection–induced dynamics cascaded by subharmonic electro-optic modulation and the four ...
