Increasingly, optical cross connects are being proposed as the basis for various photonic packet switching nodes. Combining optical switches with semiconductor optical amplifiers (SOA) has been shown to be a very effective method in creating a more scaleable cross connect which can have lower loss and crosstalk than a simple gate array. Building upon this concept, we demonstrate a very compact 4/spl times/4 (2/spl times/2 mm/sup 2/) monolithic optical cross connect using sixteen 1/spl times/2 optically amplified suppressed interference switches (OASIS) While good crosstalk suppression performance (>35 dB) was achieved, practical devices will require a reduction of the insertion loss. Two efforts devoted to this goal, namely, the addition of a spot-size convertor and a waveguide tuning mirror were demonstrated to good effect.
