All-Fiber Configuration Laser Self-Mixing Doppler Velocimeter Based on Distributed Feedback Fiber Laser
In this paper, a novel velocimeter based on laser self-mixing Doppler technology has been developed for speed measurement. The laser employed in our experiment is a distributed feedback (DFB) fiber laser, which is an all-fiber structure using only one Fiber Bragg Grating to realize optical feedback and wavelength selection. Self-mixing interference for optical velocity sensing is experimentally...
متن کاملStudy 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...
متن کاملNarrow-band generation in random distributed feedback fiber laser.
Narrow-band emission of spectral width down to ~0.05 nm line-width is achieved in the random distributed feedback fiber laser employing narrow-band fiber Bragg grating or fiber Fabry-Perot interferometer filters. The observed line-width is ~10 times less than line-width of other demonstrated up to date random distributed feedback fiber lasers. The random DFB laser with Fabry-Perot interferomete...
متن کاملMultiwavelength generation in a random distributed feedback fiber laser using an all fiber Lyot filter.
Multiwavelength lasing in the random distributed feedback fiber laser is demonstrated by employing an all fiber Lyot filter. Stable multiwavelength generation is obtained, with each line exhibiting sub-nanometer line-widths. A flat power distribution over multiple lines is obtained, which indicates that the power between lines is redistributed in nonlinear mixing processes. The multiwavelength ...
متن کاملEffect of Rayleigh-scattering distributed feedback on multiwavelength Raman fiber laser generation.
We experimentally demonstrate a Raman fiber laser based on multiple point-action fiber Bragg grating reflectors and distributed feedback via Rayleigh scattering in an ~22-km-long optical fiber. Twenty-two lasing lines with spacing of ~100 GHz (close to International Telecommunication Union grid) in the C band are generated at the watt level. In contrast to the normal cavity with competition bet...
