摘要： According to one embodiment, an optical filter has a polarization rotator and two instances of an optical bandpass filter (OBPF). The first instance of the OBPF processes a TE-polarized component of an optical input signal to produce a first filtered signal. The polarization rotator then transforms the TE polarization of the first filtered signal into the TM polarization. The polarization rotator also transforms the polarization of a TM-polarized component of the optical input signal into the TE polarization. The second instance of the OBPF processes the resulting TE-polarized signal to produce a second filtered signal. The first and second filtered signals having TM and TE polarizations, respectively, are then combined to produce a filtered output signal.

摘要： A waveguide turn having two waveguides oriented at an angle with respect to one another and optically coupled to one another by a reflective surface. In one embodiment, the reflective surface is a side of a trench formed in the core and cladding regions of the waveguides, which is designed to reflect light based on total internal reflection (TIR). The reflective surface can be designed to have an appropriate curved shape to reduce coupling losses between the waveguides. Due to relatively sharp turn (reflection) angles accessible with the reflective surface, the circuit area occupied by a waveguide turn of the invention is significantly smaller than that for a typical prior-art waveguide turn.
