QCLs were initially developed in the 1990s, and this was a significant advance in MIR light sources. 2 Standard semiconductor ...
Abstract: Fiber interferometer based on low noise lasers are crucial to the micro-vibration sensing systems. Laser noise is a key factor impacting the detection resolution of such systems. To enhance ...
Abstract: We present a novel, simple and highly effective method for generating multi-GHz regular pulse trains in lasers. This method relies on self-sustaining cross-gain modulation achieved by ...
