Port-selective wavelength demultiplexing. (a) Embedded 1x2 passthrough optimized for 1520 nm and 1580 nm through output 1, and not through output 2. (b) Embedded 1x2 demultiplexer optimized for 1530 nm through output 1 and 1570 nm through output 2. (c) Embedded bandpass filter optimized for 1550 nm through output 1, and 1540 and 1560 nm through output 2. (d) Embedded highpass filter optimized for 1530 nm through output 1, and 1540, 1550, 1560, and 1570 nm through output 2.
