We report the fabrication of tunable Bragg grating optical add/drop multiplexers (OADMs) in polymers. They exhibit 45 dB reflection with strong sidelobe suppression and no cladding-mode coupling, and they are thermally tunable at a rate of -0.256 nm//spl deg/C.
High-port-count WDM devices produced in glass optical fibers are difficult to fabricate, and as a result are quite expensive. Polymeric materials, on the other hand, offer the potential to create low-cost highly complex optical interconnection circuitry on a planar substrate. In addition, they provide the possibility for a much higher degree of ruggedness… (More)
Lithium-rich lithium niobate fabricated by vapor transport equilibration is used to frequency double the output of an injection-locked Nd:YAG laser. Internal doubling efficiencies as high as 69% and powers of as much as 1.6 W are achieved by resonant external cavity second-harmonic generation. No evidence of photorefractive damage is observed at the… (More)
