## Abstract The performance of a time‐division‐multiplexed fiber Bragg grating sensor array that uses a tunable laser source has been investigated. It was found that the wavelength detection accuracy is affected by the extinction ratio of the optical pulse modulator used for input pulse generation.

Abstract
A new system of a highly tunable visible laser source using a Gaussian pulse propagating within a nonlinear microring resonator system is proposed. Several Gaussian pulses with different center wavelengths are investigated using the designed system. The obtained results have shown that the very fine tuning wavelengths covering the visible laser wavelengths can be generated. With the very sharp peak and broad spectrum, for instance, when the Gaussian input pulse with the center wavelength at 700 nm, the spectral width of 20 pm is obtained. The interesting aspect is that the increasing in microscopic recording pen (i.e. peak) can be used to increase the imaging resolution, where the multicolor imaging, especially for multicolor bio‐cell microscopy is the target. © 2009 Wiley Periodicals, Inc.

## Abstract A photonics true‐time‐delay (TDD) system using a chirped grating and a novel fiber‐ring laser is proposed and demonstrated. A high‐birefringence fiber‐loop mirror (HiBi‐FLM) is integrated in the laser cavity to act as a polarization‐independent wavelength filter. By properly adjusting t
We demonstrate generation of continuous-wave terahertz radiation and its application to molecular spectroscopy. The radiation source is based on the photomixing of two diode laser beams in a low-temperature-grown GaAs photoconductive antenna, which offered output power of several tens of nanowatts a
The far-infrared torsional spectrum of CH 3 SiD 3 has been measured in a continuing effort to quantify the coupling between the small amplitude vibrations and the large amplitude internal rotation of the methyl group in symmetric tops.
