Twist sensor based on axial strain insensitive distributed Bragg reflector fiber laser.
A novel fiber-optic twist sensor based on a dual-polarization distributed Bragg reflector (DBR) fiber grating laser is proposed and experimentally demonstrated. By beating the signal between the two polarizations of the laser which operates at 1543.154 nm, a signal of 30.78 MHz in frequency domain is observed. The twist will change the fiber birefringence, and resulting in the beat frequency va...
متن کاملUltra-short distributed Bragg reflector fiber laser for sensing applications.
We present an ultra-short distributed Bragg reflector fiber laser written in Er/Yb co-doped fiber. The entire laser is only 8.4 mm in length. The lasing threshold is less than 1 mW. The optical signal-to-noise ratio of the laser output is better than 70 dB. The laser emits two orthogonal polarization modes and generates a beat signal with signal-to-noise ratio of approximately 70 dB and 3-dB li...
متن کاملanalysis of three section distributed bragg reflector tunable laser diode based on the transfer matrix method
we present a detailed analysis of the static tuning characteristics of three section tunable distributed bragg reflector (dbr) laser. the analysis is based on the transfer matrix method (tmm), transmission line and scattering theory. the key feature of the analysis is the use of modified oscillation condition. with the exact oscillation condition, the static tuning characteristics such as thres...
متن کاملMulti-modes Fiber Ring Laser Sensor Combining One Fiber Bragg Grating Reflector
A multi-longitudinal-mode fiber ring laser sensor is firstly proposed and experimentally demonstrated. Beat frequencies between any two longitudinal modes are used as sensing signal. The core component of the system is a multi-longitudinal-mode fiber ring cavity laser sensor based on beat frequency demodulation method. The theory of beat signal generation and strain measurement are discussed in...
متن کاملS-band multiwavelength Brillouin/Raman distributed Bragg reflector fiber lasers.
A multiwavelength Brillouin/Raman distributed Bragg reflector fiber laser operating in the S-band region is proposed and demonstrated. The laser uses a 7.7 km long dispersion-shifted fiber with an effective mode area of 15 μm(2) as the Brillouin and Raman gain media simultaneously. Two 1420 nm laser diodes with a combined power of 372 mW are used as pump sources, while a fiber Bragg grating wit...
