2
Power is coupled in between counter propagating waves The response is determined based on the grating period
3
- linearly chirped fiber bragg grating Reflection Reflection Group Delay Wavelength (µm) Reflectivity Group delay
4
Use the linear group delay to achieve optical tunable delay that can be used for demultiplexing e.g. Combine two signals in nonlinear waveguide allowing FWM to occur 10GHz and continuous wave signal-> wavelength dependent delayed signal 10GHz delayed signal and 40Gb/s data->demultiplexed 10Gb/s channels
5
Ridge or slab structure? Multi/Single mode? Bragg period? Length? Nonuniform grating Picture taken from: A. D. Simard, Y. Painchaud, and S. LaRochelle, "Characterization of Integrated Bragg Grating Profiles," Bragg Gratings, Photosensitivity and Poling, Colorado Springs, 2012.
