A pupil expansion apparatus includes: a beam splitter, configured to receive light from an optic and to replicate a pupil formed by the optic; and a waveguide, optically coupled to the beam splitter, the waveguide configured to receive light from the beam splitter and further expand the pupil.

Expanding a pupil using replication

The pupil formed by an optical apparatus is expanded by use of a beam splitter to replicate the pupil and a waveguide to further replicate the replicated pupil. An optional rotator element can rotate a portion of the light split by the beam splitter to provide consistent polarization of light in the optical apparatus. In some embodiments, the beam splitter replication expands the pupil in one direction, while the waveguide replication expands the pupil in a second direction.

A system and method for operating an electronic device used in light processing. A method comprises altering a spatial relationship between a spatial light modulator (SLM) and a light incident on the SLM, shifting light modulator states of a first portion of light modulators to a second portion of light modulators, and placing a third portion of light modulators in the SLM into a performance degradation-reducing mode. The amount of shifting performed is proportional to the amount of change in the spatial relationship. The method allows for a change in light modulators used to modulate the light, thereby preventing the overuse of some of the light modulators, which may help to prevent degradation of the light modulators. The performance degradation reducing mode may help to further reduce or even reverse the performance degradation of the light modulators.

A programmable amplifieroperable to independently adjust the amplification given to various optical signals passing through an optical fiber. An input optical fiberprovides a number of optical signals to a demultiplexer which separates each signal carried by the input fiberEach individual wavelength travels to a variable attenuatorwhich lowers the signal strength of each signal based on an input from the system controllerThe attenuated signals are combined by multiplexerand input to an optical amplifierThe optical amplifierreceives the combined signal and amplifies each signal in the combined DWDM signal across the entire bandwidth of the amplifierThe amplified signals are input to a splitterwhich removes a small portion of the entire spectrum output by the amplifierThe remaining portion of the signal passes to an output fiberand travels to the remainder of the optical network. The small portion of the signal separated by the splitteris input to a spectrum analyzerwhich detects the signal strength of each component signal traveling through the optical amplifierSignal strength information is passed to the system controllerThe system controllertypically a digital signal processor or programmable microcontroller, uses the information from the spectrum analyzerto control the variable attenuators and the gain of amplifierin order to level the various signals traveling through the amplifier
