“…Such interconnections can be used to provide massively parallel data communication among a few ports [15,36]. Most optical switch systems are constructed by the switch matrices with crossbar or tree structures [9,28]. For example, Okayama et al [28] developed an optical switch matrix with N_N tree structure by using 1_2, 2_1, and 2_2 switches.…”

“…Several all optical switching technologies have already been proposed (Nishimoto et al 1990;Fujiwara et al 1991;Okayama et al 1989). Currently available devices, such as optical-micro-electromechanical system based switches (switching time: 200 ns ∼ 1 ms) (Ollier 2002), thermal-optical switches (switching time: 1-100 ms) (Tapalian et al 2002), electrooptic switches (switching time: 5-50 ns) (Krahenbuhl 2002), and acousto-optic switches (switching time: 300 ns) (Ma and Kuo 2003) are suffering from speed limitation.…”

This paper presents an equivalent lumped element electric circuit model for traveling wave semiconductor optical amplifier (SOA) in integrated circuit applications. The model facilitates incorporation of chip and package parasitic elements of SOA. The model is used to represent an all optical 2 × 2 switch based on cross gain modulation in SOA capable of operating at an ultra fast speed. SPICE simulation of the switch with the proposed circuit model provides bit error rate (BER) values at the switch output which agrees well with the experimentally measured values at 10 Gb/s. The degradation of switching performance has been examined in terms of bit error rate, modulation bandwidth and switching time in the presence of chip parasitic elements of SOA.

The optical switch array is a key device for realizing photonic switching systems. A lossless and low crosstalk switch is the most desirable component of large‐scale switching systems which have more than 100 input/output ports. to realize such a switch monolithically, a carrier‐injection‐type optical single‐slip structure (S3) switch with traveling‐wave amplifier (COSTA) have been proposed. to realize the COSTA, a carrier‐injection‐type optical switch and an optical amplifier that are suitable for integration have been developed. First, a carrier‐injection‐type optical switch where the PN junction was formed by crystal growth was fabricated. It was confirmed that the characteristics of the device do not deteriorate during heating, which makes it suitable for integration. Next, the structure of an optical amplifier which can be integrated into the optical waveguide using the reactive ion etching (RIE) process was investigated. an optical amplifier that was integrated into a straight optical waveguide was fabricated, and it was confirmed that this amplifier could produce enough gain (internal gain of 25 dB) to compensate for the loss in the optical switch. Using these two basic techniques, a 4 × 4 COSTA was fabricated. With this 4 × 4 COSTA, fiber‐to‐fiber lossless (maximum gain of 5 dB) and extremely low crosstalk characteristics (ON‐OFF ratio of 54 dB) were demonstrated.
