“…As noted by Pearson et al [59], it may not be possible to simultaneously satisfy the single mode condition and the requirement that the waveguide have zero birefringence. When competing requirements of polarization insensitivity and minimizing bend loss make it difficult to satisfy the single mode relationship of (9), it Coupling efficiency from the fundamental ridge waveguide mode to the fundamental and higher order slab waveguide modes in a 1.5 µm thick SOI structure [59] is still possible to work with multimode waveguides provided mode filtering is used.…”

Pearson et al [59] showed that in an SOI based AWG, waveguides supporting higher order modes may be used when the waveguide bend radii are small enough that the losses for the fundamental mode are negligible while losses for the second and higher order modes are extremely large. In this case only the fundamental mode will contribute to the AWG channel spectrum.…”

Abstract. This chapter reviews the application of silicon-based planar waveguide components for wavelength division multiplexing (WDM) and demultiplexing. The polarization dependent properties and dominant waveguide loss mechanisms in both silica-on-silicon and silicon-on-insulator (SOI) waveguides are described, and the technologies developed to control loss and eliminate polarization dependence in both material platforms are presented and compared. Although less mature, the development of high index contrast devices in SOI closely parallels the evolution of silica glass waveguide technology. Many of the important design challenges have been resolved, and the performance of SOI-based integrated optic components is rapidly approaching that of the silica waveguide system.

“…To perform optical switching, total attenuation of the optical power across the grating arms is needed. This is dependent on the absorption coefficient of (9). Hence, to evaluate the dopant concentration required for switching, the spatial light impinging on the array waveguides has to be resolved.…”

Abstract-This paper reports a theoretical analysis of novel optically switched arrayed waveguide gratings (AWG) based on a silicon-on-insulator (SOI) platform using phase modulation. The phase modulation can be achieved by integrating optical phase modulators across the grating arms, incorporating four-way splitters and combiners to reduce the thermal optic effect. The phase modulator operates by injecting the free carriers to change the refractive index in the guiding region, hence allowing different wavelengths to route to different output waveguides. Also, with appropriate absorption caused by the free carriers, optical switching can be performed. We demonstrate by computer simulation the optical and electrical characteristics of the devices using a threedimensional (3-D) beam propagation method (BPM) (optical) and the two-dimensional (2-D) device simulation package SILVACO (electrical). The drive current necessary for switching the wavelength in question by one waveguide distance is approximately 0.17 mA/µm and the attenuation factor is approximately 1 dB. These devices are useful for broad application in both wavelengthdivision multiplexing (WDM) networks and photonics integrated circuits.

“…Complex photonic integrated circuits with AWGs [10,11] were successfully built and commercialized for telecom applications using the InP waveguide platform, but no similar integration level has yet been achieved in silicon waveguides. Recently, several ultra-compact AWG multiplexers have been reported using the silicon-on-insulator high refractive index contrast (∆n ~2) material platform [12][13][14][15][16]. However, in such high-index-contrast waveguides, the light intensity at the core-cladding boundary is substantially increased.…”

We experimentally demonstrate a new type of waveguide multiplexer device designed for silicon photonics, with a crosstalk level as low as −35 dB and an operational wavelength range of 300 nm. A compact device footprint of only 100 × 160 µm 2 offers an excellent potential for integration with other silicon nanophotonic circuits. ©2012 Optical Society of America References and links1. C. R.
