Paper Abstract

Cantilever couplers for fiber coupling to silicon photonic integrated circuits are presented. The couplers consist of silicon inverse width tapers embedded within silicon dioxide cantilevers that are deflected out-of plane by residual stress. Coupling efficiencies of 1.6 dB per connection for TE polarization and 2 dB per connection for TM polarization are achieved. Finite difference time domain simulations are conducted to assess coupling loss as a function of cantilever geometry and fiber-to-cantilever misalignment. The cantilever couplers enable high efficiency propagation of light from optical fibers to photonic integrated circuits directly on a chip surface without dicing or cleaving.
