“…Therefore, an optical phase control function is needed for practical application. Moreover, the phase control speed, precise phase controllability, and remote controllability are important factors, hence some methods, to optically control the phase using nonlinearities in special optical fibers, were investigated [5][6][7][8][9][10].…”

Abstract:We propose a novel optical delay interferometer (ODI) with an optically controllable phase shifter. The proposed interferometer is implemented by using a phase shifted fiber Bragg grating and an Yb 3+ /Al 3+ co-doped optical fiber. The phase of the delayed optical signal is linearly controlled by adjusting the induced pumping power of a laser diode at 976 nm. Polarization dependent loss, polarization dependent center wavelength shift and temperature induced center wavelength shift of the ODI are 0.044 dB, 6 pm, and 9.8 pm/°C, respectively.
