We consider a zero-order diffraction metallic grating having two subwavelength rectangular slits per period. The electromagnetic behavior of this system is studied theoretically in the resonance spectral domain of the cavities. We show that, by choosing judicious opto-geometrical parameters, we can perform the selective excitation of one or the other category of cavities with a very appreciable qu... View full abstract»

By using a double-sideband suppressed carrier (DSB-SC) optical transmitter and a remote self-heterodyned (RSH) detection method, we experimentally and analytically proved the feasibility of a radio-over-fiber system using a 16-QAM signal at 5 Gb/s and 18 GHz, with a transmission distance of 100 km between a mobile service center and a base station. The transmission system performance was carefully... View full abstract»

• ### Statistics of Wavelength Division Multiplexed Channels in Fiber-Optical Parametric Amplification

Publication Year: 2008, Page(s):654 - 662

| | PDF (450 KB) | HTML

The amplification of wavelength division multiplexed (WDM) data in fiber-optical parametric amplifiers give rise to cross-gain saturation and four-wave mixing crosstalk. This crosstalk affects the data quality, especially at higher input powers. The statistics in this regime are nontrivial to obtain and we present, for the first time, a model based on a combination of theory and numerics that give... View full abstract»

• ### Tunable Photonic Crystal Fiber Couplers With a Thermo-Responsive Liquid Crystal Resonator

Publication Year: 2008, Page(s):663 - 669

| | PDF (880 KB) | HTML

We theoretically address the thermo-optical response of multicore photonic crystal fiber (PCF) couplers infiltrated with nematic liquid crystals (LCs). The proposed PCF coupler consists of two identical cores separated by a third one which acts as a liquid crystal resonator. With an appropriate choice of the design parameters associated with the liquid crystal core, phase matching at a single wave... View full abstract»

In this paper, analog and digital optical pulse synthesizers using high-resolution arrayed-waveguide gratings (AWG) have been developed. The analog type of optical synthesizer consists of an AWG with an integrated 45deg, curved-surfaced mirror, a 4-f lens system, and an optically addressable spatial light modulator. The effective frequency resolution is 14.5 GHz. A dispersion compensation experime... View full abstract»

In this paper, design optimization of a SiGe/Si quantum-well optical modulator integrated on silicon-on-insulator (SOI) substrate to achieve high-frequency operation is reported. The structure, based on free-carrier depletion in a PIN diode, is integrated in a rib waveguide. Influence of geometrical parameters, layer doping, and metal contacts is determined through numerical simulations and optimi... View full abstract»

• ### Electro-Absorption Modulator Integrated Lasers With Enhanced Signal Injection Efficiency

Publication Year: 2008, Page(s):685 - 691

| | PDF (1220 KB) | HTML

By incorporating a lumped-element impedance- matching network on the laser diode carrier/submount, the signal injection efficiency of electro-absorption modulator integrated lasers is significantly improved through the reduction of input return loss. Over a frequency range spanning from 5.8 to 10 GHz, an improvement of approximately 12% to 37% in signal injection efficiency is observed. To avoid i... View full abstract»

• ### An Optically Clocked Transistor Array for High-Speed Asynchronous Label Swapping: 40 Gb/s and Beyond

We describe the development of an optically clocked transistor array (OCTA) interface device for label swapping high-speed asynchronous burst optical packets. The OCTA integrates the three critical functions of serial-to-parallel (SP) conversion, parallel-to-serial (PS) conversion, and clock-pulse generation into a simple optoelectronic integrated circuit (OEIC) to create a single-chip interface b...

An ultracompact widely tunable thermooptical (TO) microring resonator (MRR) filter based on Si nanowires is presented. The Si nanowire waveguide has a insulator, Si core, a up-cladding, and a thin metal film at the top. The metal circuit along the microring is used as a submicrometer heater which has the same width as the Si nanowire waveguide. The up-cladding is optimized to reduce the light abso...

We designed a 1.06-mum single-quantum-well (SQW) InGaAs/AlGaAs planar tapered amplifier that was injected with seed light of a fiber Bragg grating stabilized laser diode through a fiber biconical microlens. To increase the amplifier output, the microlens with approximately 3- and 11-mum radii on vertical and horizontal axes, respectively, provides high coupling efficiency between the laser diode a...

In this paper, an analytical method is proposed for calculating reflection-spectrum envelopes (RSEs) of various multipeak gratings. Consequently, impacts of parameters on the envelope of the sampled grating are analyzed in detail both with and without refractive index variation. Accuracy of those proposed methods has been verified by the good agreement with the simulated reflectivity spectrum of t... View full abstract»

• ### Pulse Distortion and Power Penalty Induced by Sinusoidal Amplitude and Phase Response Ripples for Gaussian Pulses

Publication Year: 2008, Page(s):729 - 738
| | PDF (655 KB) | HTML

The frequency responses of wavelength-selective optical components often exhibit ripples in the amplitude and/or phase. These ripples can lead to signal distortion and hence a degradation in system performance. The pulse distortion induced by sinusoidal amplitude and phase response ripples is derived for chirped and unchirped Gaussian pulses, and closed-form expressions are presented for the power...

## Aims & Scope

The Journal of Lightwave Technology is comprised of original contributions, both regular papers and letters, covering work in all aspects of optical guided-wave science, technology, and engineering. Manuscripts are solicited which report original theoretical and/or experimental results which advance the technological base of guided-wave technology. Tutorial and review papers are by invitation only. Topics of interest include the following: fiber and cable technologies, active and passive guided-wave componentry (light sources, detectors, repeaters, switches, fiber sensors, etc.); integrated optics and optoelectronics; and systems, subsystems, new applications and unique field trials. System oriented manuscripts should be concerned with systems which perform a function not previously available, out-perform previously established systems, or represent enhancements in the state of the art in general.
