Integrated photonic sensors are promising devices for various sensing applications due to their low cost, small size, and high sensitivities that can be reached. In this thesis, ring resonators and three-port Mach-Zehnder interferometer (MZI) devices fabricated on Silicon-On-Insulator were compared for …

Wereldwijd neemt de prevalentie van myopie toe. Hoog myopen hebben een sterk verhoogde kans op verschillende oculaire complicaties. Om myopie gerelateerde complicaties te voorkomen, moet vroegtijdig de myopie progressie gereduceerd worden. Deze studie onderzoekt welke behandelmethode, lage concentratie …

In this thesis the different aspects of acquiring the complex refractive index of interstellar ice analogues are treated. The ultimate aim of this work is to search for abilities to predict the infrared absorption spectra of these analogues. A key factor in these predictions is the optical influence …

Kipp & Zonen, based in Delft manufactures and develops atmospheric measurement instruments, including a scintillometer. Kipp & Zonen currently manufactures the large aperture scintillometer (LAS) MkII and previously manufactured the extra large aperture scintillometer (XLAS) MkI. A scintillometer can …

This project helps to reach the end goal of doing long distance measurements. Long distance measurements depends on the refractive index of air. The refractive index depends on temperature, pressure, humidity and gas mixture. The biggest uncertainty of calculating the refractive index is the temperature, …

This thesis describes how the abundance of CO2 a ects the porosity of H2O:CO2 ice mixtures deposited at di erent growth temperatures ranging from 30 - 70 K. The mixing ratios of the used ice samples H2O:CO2 = 10:1, 4:1 and 2:1 are of astrophysical relevance. Laser optical interference is used to monitor …
