Our dry lab cleanroom has class 100,000.


FacilitiesNumerical modelling

The simulations in Light-on-a-Chip group are running on 1) Dual CPU Intel Xeon E5-1650 6 Cores 3.5 GHz+ 64 GB DDR4 2133 MHz and on 2) AMD Ryzen Threadripper 1920X 12 Cores 3.5 GHz + 128 GB DDR4 2666 MHz. The design of devices at Light-on-a-Chip group and simulation work is carried by Maxwell solvers based on: finite element method (FEM) of COMSOL 5.2a Multiphysics with Matlab module,  finite difference time domain (FDTD) codes and Mode Solutions of Lumerical under powerful server enviroment.


VIS-SWIR High Sensitivity Imaging

We are imging the mode profiles and evaluating the propagation losses of our devices using high sensitivity digital VIS-SWIR camera: Ninox-640. It has a 640 x 512 InGaAs sensor from SCD which enables high sensitivity imaging from 0.4µm to 1.7µm. The 15µm x 15µm pixel pitch enables highest resolution VIS-SWIR image and with less than 50 electrons readout noise so the OWL 640 enables the highest VIS-SWIR detection limit. It has TEC and liquid cooling to -20°C. The Ninox 640 reduces dark current to ~1,500e/p/s, allowing longer exposures. 



World-Class Optical Performance System

We are equipped with World-Class Optical Performance Telecom spectrum analyzer system, designed to measure and display the distribution of power of an optical source over 600 to 1700 nm wavelength span: Yokogawa 6370D. It allows for high wavelength accuracy: ±0.01nm and high wavelength resolution: 0.02nm. Wide dynamic range: 78dB type. and wide level range: +20 to -90dBm, fast measurement: 0.2 sec. (100nm span). Compatible with single-mode and multimode fibers of FC/PC and AC connectors.


Ocean HDX Spectrometers

Ocean HDX spectrometer uses a robust optical bench design, optimized components and precision engineering to maximize optical resolution, increase throughput, reduce stray light and maintain thermal stability for integrated, industrial and research applications with a wavelength range of 200-1100 nm.


Supercontinuum Light Source

SuperK Extreme lasers are a series of white light lasers (WLL) systems that can generate a pulsed supercontinuum as a class 4 laser source. Using a 78 Mhz seed laser, wavelength range from 400 to 2400 nanometers (typical) are emitted in a single spatially coherent beam with a pulse rate that is customizable according to application requirements.


Tunable High Contrast Single Line Filter

The LLTF Contrast is a continuously tunable high resolution bandpass filter that effectively converts a supercontinuum source into a widely tunable picoseconds laser. The filter transmits, with high efficiency, a single laser line while blocking unwanted lines with excellent out-of-band suppression and while maintaining the intrinsic single-mode beam quality of the supercontinuum laser enabling a wide range of applications over the whole superconinuum spectrum.


Fiber-Coupled Laser System

Our Qioptiq iFLEX-iRIS™ solid state laser operates at wavelength of 637 nm with output power of 65 mW. It offers high-performance stability with low amplitude noise in a miniaturized package. In our lab, it is used for integration into instruments that demand high performance yet need to retain a small form factor. The lasers are mode-hop free and wavelength stabilized as a result of active temperature control.

Stabilized Fiber-Coupled Tungsten Light Source

Thorlabs' Stabilized Light Sources provide a constant-intensity blackbody radiation spectrum from 360 to 2600 nm. An internal feedback system is employed to achieve a highly stable power output. The superior performance of Thorlabs' stabilized light sources makes them ideal for our experiments that require high accuracy and stability, such as transmittance and reflectance measurements.
