چکیده
A distributed Bragg reflector (DBR) laser with a specially designed, heavily Er3+-doped composite fiber of length as short 1.8 cm is demonstrated. The DBR laser, pumped by 980 nm diode power up to 370 mW, generates single-frequency radiation at wavelength 1535 narrow instantaneous linewidth <100 Hz and high output 2 mW. obtained parameters pave the way toward broad range practical applications from telecommunications sensing scientific research.

Ultra-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 کاملTwist 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 کاملResonant pumped erbium-doped waveguide lasers using distributed Bragg reflector cavities.
This Letter reports on an optical pumping scheme, termed resonant pumping, for an erbium-doped distributed feedback (DFB) waveguide laser. The scheme uses two mirrors on either side of the DFB laser, forming a pump cavity that recirculates the unabsorbed pump light. Symmetric distributed Bragg reflectors are used as the mirrors and are designed by matching the external and internal quality fact...

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 کاملShort Cavity Erbium/Ytterbium Fiber Lasers Mode-Locked with a Saturable Bragg Reflector
We present short cavity erbium/ytterbium fiber lasers that are passively mode-locked with a saturable Bragg reflector. The lasers produce sub-500-fs pulses at fundamental cavity repetition rates as high as 300 MHz. Stable passive harmonic operation increases the repetition rate to 2.0 GHz. The mode-locking mechanism in both the normal and anomalous group velocity dispersion regimes is investiga...
