We propose silicon (Si)-photonics-embedded interposers to minimize the Si photonics chip size and achieve highly precise optical fiber alignment. The interposers are organic interposer substrates that have Si photonics transceiver dies buried in the

Testing of active photonic devices is totally different from testing of pure electronics; in particular, reduction of testing time in silicon photonics has been a significant issue. In this study, a compact behavioral model of optical phase shifters

We experimentally demonstrated a post-integrated dual-core spot-size converter (SSC) that had a coupling end with a 10-μm diameter at the edge of an Si-photonics chip. Although there was an extra loss increase as a result of post-integration, it can
