Optical Pulse Compression in Fiber Bragg Gratings

Optical pulse compression based on nonlinear silicon waveguides and chirped Bragg gratings

Due to the growing demand for higher bandwidth, employing optical devices instead of electronic devices in data transmission systems has attracted much attention in recent years. Optical switches, modulators and wavelength converters are a few examples of the required optical devices. CMOS compatible fabrication of these devices, leads to much more growing of this technology. Optical pulse comp...

Bandwidth compression optical processor using chirped fiber Bragg gratings

Chirped fiber Bragg gratings are used as low-loss, dispersion compensation modules for telecommunications applications. Here we use them to make an optical processor that compresses the bandwidth of electronic signals before digitization by an analog-to-digital converter. ©2007 Optical Society of America OCIS codes: (230.0250) Optoelectronics, (060.2360) Fiber optics and optical communications ...

Pulse Switching in Nonlinear Fiber Bragg Gratings

The influence of the Kerr-like nonlinearity in the switching characteristics of fiber Bragg gratings is studied. Two types of apodization profiles are considered: uniform and raisedcosine apodized gratings. The influence of the bit-rate and the wavelength detuning of the incident pulses in the nonlinear response of the grating is analyzed. The deterioration in the pulses caused by the nonlinear...

Fiber Bragg gratings in optical microfibers

Bulk regeneration of optical fiber Bragg gratings.

The reliability and reproducibility of regenerated gratings for mass production is assessed through simultaneous bulk regeneration of 10 gratings. The gratings are characterized and variations are compared after each stage of fabrication, including seed (room-temperature UV fabrication), regeneration (annealing at 850°C), and postannealing (annealing at 1100°C). In terms of Bragg wavelength (λ(...
