Monolithic quantum-dot distributed feedback laser array on silicon [PDF]

, 2018
Electrically-pumped lasers directly grown on silicon are key devices interfacing silicon microelectronics and photonics. We report here, for the first time, an electrically-pumped, room-temperature, continuous-wave (CW) and single-mode distributed ...

Long period fiber grating in two-core hollow eccentric fiber

Optics Express, 2015
Long period fiber gratings (LPGs) in a two-core hollow eccentric fiber (TCHF) have been demonstrated experimentally. Two LPGs have been fabricated into the respective core of the TCHF by a high frequency CO2 laser. The coupling characteristics in the TCHF-LPG have been studied using the coupling mode theory (CMT).

Multi‐Soliton Microcombs Enable Ultrafast Nanometric‐Precision Ranging and Photon‐Level Detection

Advanced Science, EarlyView.
Our work first demonstrates dual‐multi‐soliton ranging and confirms its multifunctional capability. The method achieves ultrafast and nanometric‐precision measurement. For practical applications, we further extend the multi‐soliton states to photon‐level ranging.

Optically Heated Long-Period Grating as Temperature-Insensitive Fiber-Optic Refractive-Index Sensor

IEEE Photonics Journal, 2012
A temperature-insensitive fiber-optic refractive-index sensor based on optically heated long-period grating (LPG) is presented. The LPG is manufactured in a short section of cobalt-doped optical fiber (COF), which can be thermally stabilized through a ...
