| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have fabricated and characterized Ti-diffused channel waveguides on Er-doped LiNbO3 (Er-LN) single crystal. A loss-compensated Ti-diffused waveguide could be realized at 1550.0 nm signal light (TM mode) by optical forward-pumping at 1484 nm with pump power of 45 mW for a 32 mm long Ti-diffused Z-cut 0.5 mol% Er-LN waveguide. As applied optical devices, we demonstrated reciprocating optical modulation (ROM) and mode-locked laser by sandwiching the phase modulator on the Er-doped LiNbO3 waveguide with two fiber Bragg gratings. Using ROM at 10 GHz, the sideband component of 50 GHz was successfully enhanced and increased by 10 dB by the optical pumping. The mode-locked laser emits pulses 3.86 ps width by driving the phase modulator at 9.27 GHz. | |
