Abstract :
We have realized an optically efficient MZ modulator for in-line RZ synchronous regeneration. Fiber to fiber loss has been measured as low as 9 dB. A deep ridge spot size converter has been implemented in the extreme passive sections as to adapt the fiber lens mode and provide larger alignment tolerance. A 6 dB optical static modulation depth has been reached with less than 0.4 dB polarization sensitivity figure of merit, and a phase modulation of 20 deg amplitude has been demonstrated possible.
