Abstract:
An optical drop filter comprising:a compression-tuned optical device including: an optical waveguide including an inner core disposed within an outer cladding and a grating disposed within the inner core, the grating reflecting a first reflection wavelength of light back alone the inner core and propagating remaining wavelengths of light through the grating, the optical waveguide including a pair of opposing surfaces; and a compressing device compresses the opposing surfaces towards each other to tune the grating to change the reflection wavelength of light reflected back along the inner core; and an optical directing device for providing an input optical signal to the compression-tuned optical device, the input optical signal having a plurality of optical channels centered at spaced wavelengths; whereby the compression-tuned optical device removes an optical channel from the input optical signal.
