Abstract
Optical wavelength division multiplexing (WDM) devices include an optical chip having a number of waveguides therein, with a common optical fiber and single wavelength channel optical fibers optically coupled to the waveguides. Wavelength sensitive filters are disposed between the chip and the fibers, or across waveguides within the chip to reflect light at certain wavelengths and to transmit light at other wavelengths. In some embodiments, all of the fibers are located at the same end of the chip, in others the common fiber is located at one side of the chip and the single channel fibers located at another side, while in others the common fiber is located at a first side of the chip and the single channel fibers are located either at the first side of the chip or at a second side of the chip.
