Optimal defect position in a DFB fiber laser

Brillouin Fiber Laser Pumped by a DFB Laser Diode

In this paper, we present a novel Brillouin fiber-ring laser utilizing an unbalanced Mach–Zehnder interferometer (UMZI) as coupling device. The laser is pumped by a distributed-feedback laser diode and shows continuous-wave and single-frequency operation. Frequency-dependent transmission characteristics of the UMZI make it possible for the pump wave to pass through the laser-ring cavity with no...

Ultra Stable Coherent Sources Based on Injection Locked Dfb from a Femtosecond Fiber Laser Comb

− We propose ultra stable coherent laser sources based on optical injection locked single mode of the femtosecond fiber laser comb. The source is discretely tunable coherent optical sources by two DFB lasers, which are injection-locked to a respective single mode of the fiber laser comb with the frequency difference of 500 MHz, that is exactly twice of the comb repetition frequency.

Study on Characteristics of Distributed Feedback (DFB) LASER as Light Source for Optical Fiber Communication System

This paper represents the study of light sources for optical communication through the optical fiber. For this purpose, the ideal light source characteristics have been studied. According to the study, the semiconductor LASER diodes are preferable sources over LEDs. From the family of LASER diodes, Distributed Feedback (DFB) lasers are considered as source. They have low threshold current and h...
