• An optical cell buffer (OCB) for use in photonic ATM switch, is needed in order to resolve contention between optical cells. A 320-Gb/s-throughput switch system with 32 wavelength channels requires a buffer size of 13 and a wave-length bandwidth of 25 nm. We developed an optical cell buffer with a four-nested-taps configuration and fabricated it with electroabsorption gates and gain clamped optical amplifiers. The output level variation, which determines the stability of operating condition, is less than 2.4 dB under typical conditions and the insertion loss variation is suppressed to within 5dB. This OCB can be used in a 320-Gb/s photonic ATM switch.
