Abstract
A concave grating design is presented that is suitable for a tunable W DM demultiplexer, Tuning is achieved by displacing the input fiber alo ng the edge of the device, The tuning feature can be used to compensat e for inevitable variations in wafer fabrication or to shift the set o f channel wavelengths to match a particular WDM transmitter, An effect ive index error of about one percent can easily be accommodated.
