Fix-Wavelength Multi-Analyte Detection with Serial SOI Ring Resonators

Wavelength Tunable Laser with Silica-Waveguide Ring Resonators

We have proposed a tunable laser with silica-waveguide ring resonators. In this tunable laser, a semiconductor optical amplifier was passively aligned and mounted onto a silica-waveguide substrate. The ring resonators can be tuned by controlling their temperatures using the thermo optic heaters formed on them, and there are no mechanically moving parts. Thus, they are sufficiently stable and re...

Wavelength Demultiplexer using Heterostructure Ring Resonators in Triangular Photonic Crystals

In this paper a new type of wavelength demultiplexer using ring resonators in 2D triangular photonic crystal is presented. The designed demultiplexer contents two regions which each own a resonator. Two dielectric constants are used in this demultiplexer. These structures which are called hetero have the capability to be used in wavelength division multiplexing (WDM) systems. The average transf...

Mapping the sensitivity of split ring resonators using a localized analyte

Athermal silicon ring resonators clad with titanium dioxide for 1.3µm wavelength operation.

We investigate the athermal characteristics of silicon waveguides clad with TiO(2) designed for 1.3 µm wavelength operation. Using CMOS-compatible fabrication processes, we realize and experimentally demonstrate silicon photonic ring resonators with resonant wavelengths that vary by less than 6 pm/°C at 1.3 µm. The measured ring resonance wavelengths across the 20-50°C temperature range show ne...

High temporal resolution of the ring down of SOI wire racetrack resonators

Measuring the transmission of the waveguides (for a continuous wave (CW) input), can yield directly the resonant frequencies of the racetrack and their quality factors. In the case of dynamically actuated samples such inferences are not so simple. We therefore investigate the ability of the temporally precise and background free method of optical parametric amplification, to resolve the respons...
