Pulses from an ultrafast oscillator are conditioned, amplified, and delivered in an all-optical-fiber architecture. Combined with an electro-optic receiver, the complete system delivers a 4-V electrical trigger with less than 400 fs additive jitter.
We demonstrate for the first time the low penalty cascaded performance of a 1.3mum QD SOA. Eleven passes are feasible for 10Gb/s data while maintaining a Q-factor exceeding 6 for filter-free operation.
The composition-spread approach provides a means for evaluating the maximum photoluminescence in new systems of erbium-containing oxides. Hundreds of combinations of zinc-, bismuth-, gadolinium-, and aluminum-substituted SiO2 are evaluated; the Er:Zn-Ge-Si-O system is particularly promising.
Performance of tunable buffers based on optical amplifiers and its improvement using gain flattening is analyzed. A simple analytical expression indicates that to store more than a couple of bits unrealistically high gain is required.
We report optical amplification in a bismuth-doped silica fiber at 1308 nm with 810 nm excitation and demonstrated simultaneous optical amplification at two wavelengths near 1300 nm region. This wavelength is the closest to the important telecommunications window.
Near infrared emission with a bandwidth more than 450 nm which should be useful for ultra broadband optical amplifiers and tunable lasers for optical telecommunication, has been observed from Bi-doped lithium alumino silicate glass.
Optical parametric chirped pulse amplification provides a promising alternative for amplification of high-power few-cycle pulses. Our objective is to explore the feasibility of this concept in amplifying 7 fs phase-stabilized pulses till 10 TW power.
All-optical AND and NAND gates have been demonstrated in a Ti-diffused periodically poled LiNbO3 channel waveguide which has two second phase-matching peaks by cascaded sum frequency generation/difference frequency generation and sum frequency generation processes.
