摘要:
The present invention relates to an optical signal processing apparatus and optical signal processing method which enable generation, waveform shaping, waveform measurement, waveform recording, correlation processing, and the like of optical pulses of 1-10 ps. A basic construction of the optical signal processing apparatus includes an optical waveguide (9), (13), (22), (26), (33), (37), (41), (56), a first means (2), (10), (14), (25), (36), (42), (57) for equally distributing output light of the optical waveguide, an optical waveguide comprising an aggregate of optical waveguides changing in optical length by a constant interval, an arrayed waveguide (3), (11), (15), (24), (32), (43), (58) for dividing the output light, second means (4), (12), (16), (23), (34), (35), (59) for focusing optical output of the arrayed waveguide, and a mirror (110), (402), (2021), (2048), (2115) for receiving and reflecting incident light focused by the second means. Or, the apparatus includes an optical waveguide, first means for equally distributing output light of the optical waveguide, an arrayed waveguide comprising an aggregate of optical waveguides changing in optical length by a constant interval for dividing the output light, second means for focusing optical output of the arrayed waveguide, and a spatial filter (5), (17), (109) for receiving light focused by the second means to distribute the incident light on a straight line and making desired amplitude or phase modulation of the light according to the position on the straight line and reflecting the light.
