Tunable holographic second-harmonic generators in high-birefringence optical fibers.
The formation of efficient holographic second-harmonic generators in high-birefringence phosphorus-doped germanosilicate fibers is reported. The influence of optical polarization on the nonlinear writing and read-out processes is explored. Fiber birefringence permits phase-matched second-harmonic conversion at wavelengths within +/-125 cm(-1) (+/-14 nm) of the writing wavelength (1.064 microm).
