²
optical transceiver module for optical interconnection has been developed. To obtain a compact optical module suitable for chip-to-chip interconnection, a lens integrated connector, a small low temperature co-fired ceramic (LTCC) package, and a precise lens assembling technology were used. Experimental results showed that the proposed module can achieve 25 Gb/s error free transmission.
