TLDR
In this paper, a metal heater, deposited on the top of a SOI rib, generates thermal energy and is assumed that the waveguide structure is infinite in extent in the direction of the propagating wave (into the page).Abstract:
In the proposed thermo optic modulator a metal heater, deposited on the top of a SOI rib, generates thermal energy. It is assumed that the waveguide structure is infinite in extent in the direction of the propagating wave (into the page). Consequently longitudinal heat flow can be neglected and only the cross-sectional temperature distribution is studied. Heat transfer from the heater to the air cladding is also neglected. By controlling the electrical power applied to the heater the temperature profile inside the structure, and hence the associated change in refractive index, can be calculated. The present paper focuses on the thermal design.read more

Silicon and polymer nanophotonic devices based on photonic crystals
TL;DR: In this paper, an ultra-compact silicon modulator was experimentally demonstrated based on silicon photonic crystal waveguides, which achieved modulation operation by carrier injection into an 80-micron-long silicon PhC waveguide of a Mach-Zehnder interferometer (MZI) structure.

Silicon-on-insulator-based photonic-crystal mach-zehnder interferometers
TL;DR: In this article, the active control of photonic crystal waveguides (PCW) incorporated in Mach-Zehnder interferometers has been investigated in order to enhance the heat exchange efficiency between the source and the active PCW region.

Optical Y-junction power splitter
TL;DR: In this article, the authors investigated how an asymmetric Y-junction behaves as a power splitter using switching function called Thermo Optic Effect (TOE), which is based on how heating of one of the arms change its refractive index leading to low crosstalk, insertion loss, low driving power, coupling length and optimum switching characteristics.

Investigation of temperature prolife in the waveguide
TL;DR: In this article, the authors investigated the temperature profile in the thermo-optic waveguide using one and two-dimensional model to analyze the thermal model and found that heating the heater will change the refractive index and change the profile in waveguide.
