Abstract

We analyze 45 degree(s) Self-Aligned Integrated Mirrors (SAIM) with Finite-Difference Beam Propagation Method. For the first time, we compare the intrinsic losses of three self-aligned structures that are used in integrated optics or optical interconnection circuits. We underline trade-off to make between diffraction and part of reflected power in the choice of self-aligned structures. We consider monomode polyimide optical waveguides and propagation in both quasi-TE and quasi-TM polarization modes. Comparisons are also made with semiconductor optical waveguides. It is shown that, in both cases, intrinsic losses of SAIM can be lower than 0.05 dB. This result is promising for the fabrication of future complex photonic circuits including several ten of mirrors.
