“…The frequency response of the different channels follows from the overlap of this field with the modal fields of the receiver waveguides. If we assume that the focal field is a good replica of the modal field at the input, and that the input and output waveguides are identical, the (logarithmic) transmission around the channel maximum follows as the overlap of the modal field with itself, displaced over a distance (12) in which is the normalized modal field, is the dispersion as defined in (3) and is the transmission in dB at the channel maximum. For small values of (smaller than the effective mode width ) the overlap integral can be evaluated analytically by approximating the modal fields as Gaussian fields (13) The -dB bandwidth is twice the value for which dB (14) The latter identity follows by substitution of .…”

This paper describes the use of integrated heaters and closed-loop applications for temperature control of planar waveguide circuits. The history of arrayed waveguide gratings (AWG) temperature control is discussed along with the difficulties in applying this control. Modeling and measurement results for external and integrated heaters will be presented. Fundamental considerations as well as modeling and measurement of the thermal characteristics of various physical constructions are discussed, and the rationale for applying these disciplines to a given problem is highlighted. In this work, we will present the evolution of these unique integrated thin film heaters and review thermal-optical modeling to experimental demonstration of the AWG. The goal of the work is to provide a solution path for integration of multiple optical devices on a single substrate from a thermomechanical as well as optical discipline point of view.Index Terms-Arrayed waveguide grating (AWG), center wavelength (CW), dense wavelength division multiplexing (DWDM), index, optical network, optical waveguide, planar lightwave circuits (PLC), sensor, temperature control, thermistor, thin-film heater, variable optical attenuator (VOA).

“…Inorganic materials are widely used for modern integrated optics due to their excellent thermal stability, chemical inertness, transparency and low birefringence [4][5][6][7][8][9][10][11]. However, these materials have the disadvantage of a high production cost compared with other materials.…”

This paper presents our recent results on the materials science and engineering research that we are pursuing for what we call very large scale integrated (VLSI) micro=nano-photonic circuit applications and optical printed circuit board (O-PCB) applications. It discusses on the design and fabrication of optical waveguides and photonic devices to be part of the micro=nano-photonic integration for VLSI photonic integrated circuits of generic and application-specific nature. The optical circuits consist of 2-dimensional planar arrays of micro=nano-optical wires, circuits and devices to perform various functions. The integrated optical circuits are primarily made of polymer and silicon materials. We present the use of organic-inorganic hybrid materials for micro-scale optical waveguide fabrication and discuss various attempts to vary the optical properties such as refractive indices, transmission windows, losses, birefringence, dispersion, nonlinearity, thermal=mechanical stability, and related issues. These waveguides and devices are considered particularly useful for O-PCB fabrication. We then present the use of silicon as a basic material for VLSI photonic devices. We discuss their properties and advantages for nanoscale functional waveguides and devices for VLSI photonics. We will look into the use of silicon materials as the basis for the building blocks of VLSI photonics. We will finally discuss the issues regarding how these building blocks can be put together for integration for O-PCB and VLSI photonic chips.
