We present a tunable optical delay line based on the use of a single chirped fiber Bragg grating written into a standard single mode optical fiber. In the proposed scheme, the delay is induced through the Bragg grating differential group delay curve. This is achieved by launching orthogonally polarized optical pulses in both directions into the Bragg grating and by controlling its local birefri...

We show that taking into account the temporal intensity profile of a pulsed pump beam may lead to significant deviations from the predictions based on a continuous wave analysis of the modulation instability process occurring in a dispersion oscillating fiber operating under the conditions that lead to gain sideband splitting. Potential application to a pulse doubling scheme with tunable delay ...

We demonstrate a method for all-optical, tunable pulse repetition-rate multiplication of a mode-locked laser based on spectral line-by-line control. In particular, two-to-five-times repetition-rate multiplication of a 9 GHz source is achieved with very high fidelity.

a series of two experiments was conducted to study the optimum dietary protein level and protein to energy ratio of lemon fin barb hybrid larvae. in experiment 1, five isocaloric diets (4700 kcal per kg) ranging from 40 to 60% protein in 5% increments were fed to triplicate groups of lemon fin barb hybrid larvae (initial weight: 0.10 ± 0.01 mg per fish) for 21 days. weight gain of fish was prop...

In this contribution a tunable via-free microstrip composite right/lefthanded transmission line (CRLH-TL) is designed and simulated. To add tunability RF MEMS elements are implemented in the interdigital capacitors and stub inductors, which match the line impedance during tuning. The via-free design enables easy and low-cost fabrication. Additionally, tunable zero-order resonators (ZORs) using ...

A continuous single-frequency tunable blue laser at 447.3 nm is developed by external-cavity frequency doubling of a tapered amplifier-boosted continuous-wave diode laser at cesium (Cs) D1 line. A maximum blue power of 178 mW with 50.8% conversion efficiency is obtained. It can be continuously tuned over a range around 1.6 GHz as the diode laser frequency is scanned across the F=4→F'...
