Latest Patents
One of his latest patents is titled "Efficient Sampled Bragg Gratings for WDM Applications." This invention presents techniques for designing efficient gratings with multiple frequency response channels based predominantly on phase modulation of the underlying grating structure. Each period of the phase sampled patterns may include contiguous, discrete phase segments with different phase values, or alternatively, a continuous spatial phase pattern that changes the phase of the underlying grating structure. Moderate amplitude modulation of the underlying grating structure by the sampling structure may also be used together with phase modulation. The grating period or the sampling period may be chirped.
Another significant patent is "Diffraction Compensation of FBG Phase Masks for Multi-Channel Sampling Applications." This invention is directed to a system and method for designing efficient multi-channel FBG gratings using a pre-compensated phase mask for diffracting light for side-writing the grating on an optical fiber core. A desired phase function of the FBG is generated, specifically tailored to an effective spacing between the phase mask and the optical fiber core. From the phase function, a phase mask is pre-compensated to offset diffraction effects associated with each longitudinal position of the FBG receiving light from two corresponding longitudinal positions of the phase mask, which are substantially symmetrically spaced longitudinally relative to each particular longitudinal position of the FBG.
