Abstract :
A wide-angle low-loss single-mode symmetric Y-junction with a pair of integrated microprisms is proposed. The microprisms compensate the phase mismatch caused by branching to reduce the radiation loss. Device performance is examined numerically by the beam propagation method. The results show that the transmission loss can be less than 0.81 dB even if the branching angle is as large as 20/spl deg/. Moreover, a simple rule is presented for the design of the prisms.<>
