This paper investigates an analytical model of a system consisting of a photonic crystal waveguide, a microcavity, and a four-level electromagnetically-induced transparency atom. The transmission and reflection of the system are numerically calculated, and it shown that classical results for this class of systems can be extended to the quantum regime. In particular, these systems could enable u...

All-fiber optical parametric oscillator (FOPO) has received considerable attention throughout these years. In this paper, we review the basic theory—four wave mixing (FWM) in the optical fibers, which leads to the parametric amplification. Phase matching condition is then discussed, with emphasis on the phase matching near the zero dispersion wavelength. In the end, recent developments on FOPO ...

All-optical, mirrorless switching and bistability is demonstrated with bacteriorhodopsin (bR). A low-power, 532 nm laser beam modulates the transmission of a cw laser beam at 635 nm that corresponds to peak absorption of the Oexcited state in the bR photocycle. The switch has features like a NOT-gate; its switching contrast depends on the pulse width and average power of the modulating laser. T...

Using analytical modeling and detailed numerical simulations, we investigate properties of hybrid systems of photonic crystal microcavities which incorporate a highly nonlinear ultraSlow light medium. We demonstrate that such systems, while being miniature in size sorder wavelengthd, and integrable, could enable ultrafast nonlinear all-optical switching at ultralow seven single photond energy l...

We demonstrate that 80 Gb/s data-packets can be all-optically switched into two different ports employing an optical wavelength converter controlled by a monolithically integrated optical flip-flop memory. The optical wavelength converter consists of a semiconductor optical amplifier and an optical filter. The integrated optical flip-flop exhibits single-mode operation, has 35 dB contrast ratio...

The first generation of optical networks employed primarily static point-to-point WDM systems to provide increased network capacity. Optical networks using WDM are now widely deployed in carrier networks, particularly in long-haul networks. For the most part, these point-to-point WDM systems provide tens of wavelengths worth of capacity over a single fiber pair, with each wavelength operating a...

A ll-optical signal processing attracts much attention because of its potential to overcome the bandwidth and speed bottlenecks of electronic circuits. Many all-optical signal processing techniques already show up in a wide range of applications, like ultrafast telecommunications, optical computing, microwave photonics and biophotonics. These techniques offer processing bandwidths up to several...
