Abstract

An optical filter (100), including a Bragg grating (102), is compression tuned such that when under one compressional load (or no load) the grating (102) has a first profile and under a second compressional load the grating (102) has a second profile. One application is to allow the grating filter function to be parked optically between channels of a WDM or DWDM optical system.
