| Abstract(in English) | In order to realize dynamic optical path networks that transmit coarse-granular video traffics with ultra-low energy consumption, we have developed optical path switches based on silicon photonics technology. This paper reports an ultra-compact 32×32 path-independent-insertion-loss optical switch based on Si-wire waveguides. For scaling the port count of the optical switch, uniformity of the fabrication process and packaging technology for large number of electronic I/O are essential. We introduce advanced fabrication process using ArF immersion lithography on a 300-mm SOI wafer and flip-chip packaging technology using a ceramic interposer with a 0.5-mm pitch land grid array for the 32×32 optical path switch. The intra-die uniformity is highly improved, resulting in the estimated crosstalk of -20 dB and the on-chip loss of 15.8±0.8 dB. The flip-chip packaging enables two-dimensional arrangement of the pads on the chip, and small die footprint of 11×25 mm2 is achieved. |
