Narrow Linewidth Distributed Feedback Lasers Utilizing Distributed

Canadian DFB Distributed Feedback Laser 400G

Covering NIR to LWIR wavelengths (750nm–17µm), these lasers feature integrated DFB gratings and TEC cooling for robust thermal management and low-noise performance across diverse conditions. A distributed-feedback laser (DFB laser) is a laser where the whole resonator consists of a periodic structure in the laser gain medium, which acts as a distributed Bragg reflector in the wavelength range of laser action. The structure builds a one-dimensional interference grating (Bragg scattering), and the.

Sagnac Interferometer Distributed Fiber Optic Sensing

We demonstrated a fiber optic distributed acoustic sensor based on a double Sagnac interferometer, using two wavelengths separated by CWDM modules. The polarization-maintaining fiber (PMF) is spliced between two single mode fibers (SMFs) to form the SMF-PMF-SMF (SPS) fiber structure.
