OPTICAL DEVICE FOR DISPERSION COMPENSATION

摘要

An optical device for receiving input light (170) and for acting on the input light to produce output light (172) includes a first reflector (165) and a second reflector (163) supported in a spaced-apart, confronting relationship with the first reflector such that the input light received by the optical device, at least potentially, undergoes multiple reflections between the first and second reflectors. At least a selected one of the first and second reflectors is configured to subject each one of the plurality of different portions of the input light to one of the plurality of different reflectance values to produce an emitted light passing through at least the selected reflector in a way which is combinable to generate the output light.
