| Summary: | A self-aligned photonic coupler, consisting of a tapered fiber and a suspended rectangular waveguide, is presented as a new approach for optical interfacing from SMF fiber domain to integrated photonic domain. The alignment occurs due to optical forces and a theoretical maximum transmitance of -1.4dB as well as significant attractive optical force range of 1.25?m for 1mW of input power are demonstrated. For a non-optimized geometry of 660nm taper diameter and 240x220nm waveguide, this result already matches transmitance for typical approaches for this interfacing with advantages of coarser alignment complexity and polarization and bandwidth flexibility. |
