摘要： An optical device includes a light-transmitting medium positioned on a base. The light-transmitting medium at least partially defines a free propagation region through which light signals travel. A reflective grating includes stepped reflecting surfaces positioned such that light signals that travel through the free propagation region are received by the reflecting surfaces. The reflecting surfaces are configured to reflect the light signal back into the free propagation region such that the light signals associated with different wavelengths separate as the light signals travel through the free propagation region. At least a portion of the reflecting surfaces each includes an overlapping region. Additionally, at least a portion of the reflecting surfaces each includes an overlapped region and un un-overlapped region. The reflecting grating is configured such that the light signals travel toward the overlapped regions and the un-overlapped regions before being reflected. The un-overlapped regions are positioned such that the un-overlapped regions receive the light signals but the overlapping regions are positioned between the overlapped region and the light signals so that the overlapping regions receive the light signals before the light signals can be received by the overlapped regions.

摘要： An optical device for splitting up a multi-wavelength light beam into a plurality of individual beams, each comprising light of a different wavelength or a narrow beam of wavelengths. The optical device includes an optical grating and an optical system for directing the incident beam onto the optical grating. The incident beam is divided into two portions, and one portion is directed onto the grating in one direction, while the other portion is directed onto the grating along an opposite direction. Preferably the grating is formed in two parts and one beam portion is directed through the two grating parts in succession in one direction while the other beam portion is directed through the two grating parts in succession along an opposite direction. A common mirror may be used to direct light towards the grating and to receive light returning from the grating. The device may also be used as a multiplexer by reversing the direction of light transmitted through the device.
