Abstract
To provide DARPA with a high-resolution (>8 bits) optical time delay module exhibiting low optical insertion loss (< 3 dB) and fast reconfiguration time (< 10 micro-seconds), Omega Optics proposes a low-loss, fast-tuned true time delay (TTD) module based on dispersion enhanced photonic crystal fiber (PCF) in conjunction with a fast wavelength tunable laser. Low insertion loss of 3 dB is achieved through the employment of conventional fiber numerical-aperture matched PCF connection, which is to be designed and fabricated in this program. Also, due to the enhanced dispersion (D > -2500 ps/nm¿km), time delay from 0s to 10ns can be continuously obtained with less than 80m PCF within a wavelength tuning range of 50nm at 1550nm while maintaining a switching time faster than 10 micro-seconds. Compared with highly dispersive silicon fiber (D ~ -100 ps/nm¿km), the total length needed is shortened by 25 times. Consequently, the overall volume and weight is decreased by 25 times. To prove the feasibility of the TTD module, the design and fabrication of highly dispersive PCF and fast tunable laser, and the characterization of the TTD module will be performed to achieve the system goal. Success of these tasks will lay a solid foundation for the phase II and phase III continuation.
