“…Although PCF-based OTDM demultiplexers were demonstrated by exploiting XPM in the PCF [13][14][15] and optical logic gates using a triple-core PCF were also theoretically studied [24], they did not have a capability of wavelength multicasting. On the other hand, there has been an intensive research on the use of PCFs for wavelength conversion and multicasting [22,23,[25][26][27], respectively, while OTDM demultiplexing was not considered in such reported works. With the increasing demand on video conferencing, HDTV distribution, and HD video-ondemand, WDM networks are required to possess an important function of wavelength multicasting that allows the same data signal to be transmitted at multiple selected wavelengths and to be distributed over the network to multiple destinations [2,23,[25][26][27][28][29][30].…”

If we can improve the design of conventional OTDM demultiplexers by providing an additional function of wavelength multicasting with no increase of complexity, the applicability of OTDM networks should be enhanced.…”

This paper reports a new design of optical time-division multiplexed (OTDM) systems that possess a functionality of simultaneous time demultiplexing and wavelength multicasting based on the cascaded four-wave mixing in a dispersion-flattened highly nonlinear photonic crystal fiber (DF-HNL-PCF). A module of OTDM demultiplexing and wavelength multicasting can be feasibly implemented by using a 3 dB optical coupler, a high-power erbium-doped fiber amplifier, a short-length DF-HNL-PCF, and a wavelength demultiplexer in the simple configuration. We also carry out an experiment on the proposed system to demonstrate the 100–10 Gbit s−1 OTDM demultiplexing with wavelength conversion simultaneously at 4 multicast wavelengths. It is shown that error-free wavelength multicasting is achieved on two wavelength channels with the minimum power penalty of 3.2 dB relative to the 10 Gbit s−1 back-to-back measurement, whereas the bit error rates of other two multicasting channels are measured to be about 10−6–10−5. Moreover, we propose the use of a proper error-correcting code to improve the multicasting performance of such an OTDM system, and our work reveals that the resulting system can theoretically support error-free multicasting of the OTDM-demultiplexed signal on four wavelength channels.

A tunable non-polarizing optical bandpass filter structure, comprising a prism pair coupled planar optical waveguide (POW), is demonstrated, by changing the incident angle of the filter. Experimental measurements show that pass bands for both TM and TE polarized waves are present in the filter simultaneously, and the two passbands overlap on each other. The overlapping of the two passbands can be sustainable for the peak wavelength from 623 to 852 nm as the incident angle of the light tuned within 2°. This POW based optical bandpass filter can be potentially applicable in various fields of optical and laser spectroscopies.

Photonic crystal fiber is a category of optical fibers, getting great attention by its promise to offer a range of optical characteristics that are not achievable in conventional optical fibers. Engineered dispersion and nonlinear characteristics of photonic crystal fiber (PCF) make it an attractive candidate for nonlinear optics and advanced optical networking in the all-optical domain. An optical network consists of different optical components such as laser sources, amplifiers, regenerators, and convertors for proper signal transmission over long distances. In recent years, the performance of the components has been improving by employing the appealing properties of PCF. The PCF’s application on such components is discussed, and the simulated results on gain amplification, regeneration, conversion, fiber laser are reviewed. These developments reveal that the enhanced performance provided by PCF makes it suitable for different optics applications.
