活动简介

报告简介

        Telecom fibers are designed for high speed communication transmission over long distances. They have advantages of low loss, low nonlinearity and easy to handle. However they are not designed for fiber based components; the most famous fiber device is the Fiber Bragg Gratings (FBGs), which was fabricated by phase mask with equal spatial period index modulation on telecom fibers to enhance coherent property of the light source as a narrowband filter. Here I will talk about a different technique to manipulate the coherence of the light source by enhancing fiber scattering with random index modulation periods to replace laser cavity mirrors,  the irregular periods formed local interference pattern over a few centimeters fibers generating “massive modes”, which in fact gives ultra-narrow linewidth laser, the massive modes also create real time Gb/s random number generation, simultaneous high order Stokes waves lasing as frequency comb, tunable microwave generator, and multi-parameter sensing.
