The CMOS compatible fabrication equipment, the transparency from UV to IR and the capability of batch processing make the TriPleX™ waveguide platform very suitable for a large variety of applications. In this paper a description of the technology and examples of applications in different wavelength ranges are given. These applications exploit the low loss properties at relatively high index contrasts in the TriPleX™ technology © 2011 IEEE.

A novel and simple approach to optical wavelength measurement is presented in this paper. The working principle is demonstrated using a tunable waveguide micro ring resonator and single photodiode. The initial calibration is done with a set of known wavelengths and resonator tunings. The combined spectral sensitivity function of the resonator and photodiode at each tuning voltage was modeled by a neural network. For determining the unknown wavelengths, the resonator was tuned with a set of heating voltages and the corresponding photodiode signals were collected. The unknown wavelength was estimated, based on the collected photodiode signals, the calibrated neural networks, and an optimization algorithm. The wavelength estimate method provides a high spectral precision of about 8 pm (5·10-6at 1550 nm) in the wavelength range between 1549 nm to 1553 nm. A higher precision of 5 pm (3·10 -6) is achieved in the range between 1550.3 nm to 1550.8 nm, which is a factor of five improved compared to a simple lookup of data. The importance of our approach is that it strongly simplifies the optical system and enables optical integration. The approach is also of general importance, because it may be applicable to all wavelength monitoring devices which show an adjustable wavelength response. © 2013 Optical Society of America.

Photonic Integrated Circuit technology for visible light can enable new applications which are not possible to realize with existing discrete components. In this paper we will show several examples of passive and active optical functions based on our new waveguide technology for visible light. Examples like wavelength combiners, power splitters, switches, filter components, variable attenuators and modulators demonstrate that the creation of new functionalities and applications become possible by combining more visible-light on-chip functions on a single platform. © 2015 Elsevier B.V.

We report on the spectral properties of a diode laser with a tunable external cavity mirror, realized as an integrated optics waveguide circuit. Even though the external cavity is short compared to that of other narrow bandwidth external cavity lasers, the spectral bandwidth of this tunable laser is as small as 25 kHz (FWHM). The side-mode suppression ratio (SMSR) is 50 dB. The laser is able to access preset wavelengths in 200 μs and can be tuned over the full telecommunications C-band (1530-1565 nm). © 2013 Astro Ltd.
