“…As a fabrication method for this array waveguide, the authors investigated selective organometallic vapor phase growth [6]. Devices fabricated by selective growth include a laser with the width of the selective growth mask varying along the resonator direction and a modulated integrated optical source [7].…”

SUMMARYThis paper proposes an optical deflector using an arrayed waveguide with a staircase-like refractive index profile. This device is an optical deflector using an array waveguide with the refractive index different in each of the component waveguides. Optical deflection is accomplished by application of a voltage. In order to study the deflection properties, a theoretical analysis of the structure, device parameters, deflection angle, and number of resolution points is carried out. As a method of realizing an arrayed waveguide with built-in refractive index steps, selective organometallic vapor phase epitaxial growth is used for fabrication of an array waveguide with multiple quantum well structures. Initial experimental results are reported here.

“…In SAG, the substrate is patterned by dielectric masks, on which any nucleation is avoided. Because deposition happens only in the openings, the growth rate of materials is enhanced and the composition of the material is also different from that on bare substrates [14]. The geometry of mask patterns including mask width and separation can then be used to tune the effective index (n eff ) of the SAG materials.…”

“…Fig.1 show schematic design of the wavelength selective switch which consists of input waveguide, two identical star coupler, arrayed waveguides, and output waveguides. The arrayed waveguides was fabricated by selective metal-organic vapor phase epitaxy (MOVPE) growth using the asymmetric SiO 2 mask pattern on both sides of the array [5,6]. In addition, the input waveguide, the star coupler, and the output waveguides also were fabricated by selective MOVPE grwoth.…”

Four wavelength switching was successfully demonstrated in the wavelength selective switch using GaInAs/InP MQW variable index arrayed waveguide by thermo-optic (TO) effect. Four wavelength lights were switched and demultiplexed between the four output ports. IntroductionIn WDM networks, key components are the wavelength multi-/demultiplexers, which combine/separate wavelength channels. Various kind of demultiplexing principles have been proposed and already commercially available, such as arrayed-waveguide gratings (AWG). In the latest paper, a novel wavelength demultiplexer using a GaInAs/InP multiple quantum well (MQW) arrayed waveguide has been proposed in which refractive index varies linearly across the array [1,2]. The conventional AWGs are designed so that phase differences between adjacent waveguides are obtained by gradually varying waveguide length. In the proposed design, however, phase differences between adjacent waveguides are achieved by varying the waveguide thickness which is the refractive indices of the waveguides. Therefore, it is possible to be realized a straight waveguide type wavelength demultiplexer [2]. Furthermore, the device could be applied to wavelength selective switch since the refractive indices of the waveguides in the array can be controlled dynamically by TO effect or QCSE [3,4]. In this report, we show the successful wavelength switching in the wavelength selective switch with linearly varying refractive index arrayed waveguide by controlling the refractive index using TO effect.
