Abstract: A first waveguide and a second waveguide including a first layer and a second layer are provided. In a first longitudinal segment, the first layer gradually approaches a first waveguide in a first transverse direction. In a second longitudinal segment, the first and second waveguides are longitudinally oriented. In a third longitudinal segment, the first layer includes a length portion having a width in the first transverse direction that gradually decreases along the third longitudinal segment, and the second layer includes a length portion having a width in the first transverse direction that gradually increases along the third longitudinal segment.

Abstract: A method and apparatus are provided. The method includes receiving, at a TE0 mode add/drop filter, a TE0 mode optical signal having a first wavelength and a second wavelength, and transmitting, from the TE0 mode add/drop filter, the TE0 mode optical signal having the first wavelength and the second wavelength towards a Bragg grating, without converting the TE0 mode optical signal having the first wavelength and the second wavelength to another mode. The method further includes receiving, at the TE0 mode add/drop filter, a reflected TE1 mode optical signal having the first wavelength from the Bragg grating, and transmitting, from the TE0 mode add/drop filter, the reflected TE1 mode optical signal having the first wavelength towards a photodetector, without converting the reflected TE1 mode optical signal having the first wavelength to another mode.

Abstract: A device and method are provided. The device includes a bus waveguide having a longitudinal axis, a lower waveguide disposed on a first side of the bus waveguide, and an upper waveguide disposed on a second side of the bus waveguide opposite to the first side of the bus waveguide, wherein the upper waveguide substantially matches a path of the lower waveguide. The method includes receiving a TE1 mode optical signal on a bus waveguide, receiving a TE0 mode optical signal on a lower waveguide disposed below the bus waveguide, mode multiplexing the TE1 mode optical signal and the TE0 mode optical signal without converting the TE0 mode optical signal or the TE1 mode optical signal to another mode, and outputting the TE0 mode optical signal and the TE1 mode optical signal on the bus waveguide.
