Hei, K. (author), Shi, Guang (author), Hänsel, A. (author), Deng, Z. (author), Latkowski, Sylwester (author), Van Den Berg, Steven A. (author), Bente, Erwin (author), Bhattacharya, N. (author)The measurement of distance plays an integral part in many aspects of modern societies. In this paper an integrated mode-locked laser on a chip is used for distance measurement based on mode-resolved interferometry. The emission from the on-chip source with a repetition rate of 2.5 GHz and a spectral bandwidth of 3 nm is coupled into a...journal article 2019

Hänsel, A. (author)Spectroscopy is a powerful tool to investigate the physical properties of complex systems. The interaction of light with matter allows to get insights into the structure of it. Chapter 1 is dedicated to introduce this topic and to show the developments of the technologies that paved the way to its success. Special focus is given to the...doctoral thesis 2018

J A (author), Ambrosius, H. P M M (author), Smit, M (author), Williams, KA (author), Bente, E.A.J.M. (author)In this paper a generic monolithic photonic integration technology platform and tunable laser devices for gas sensing applications at 2 μm will be presented. The basic set of long wavelength optical functions which is fundamental for a generic photonic integration approach is realized using planar, but-joint, active-passive integration on...conference paper 2017

J A (author), Ambrosius, H. P M M (author), Smit, M (author), Bente, E.A.J.M. (author)We present a widely tunable extended cavity ring laser operating at 2 μm that is monolithically integrated on an indium phosphide substrate. The photonic integrated circuit is designed and fabricated within a multiproject wafer run using a generic integration technology platform. The laser features an intracavity tuning mechanism based on...journal article 2016

Šmíd, R. (author), Hänsel, A. (author), Pravdová, L. (author), Sobota, J. (author), Cíp, O. (author), Bhattacharya, N. (author)In this work we present a design of an external optical cavity based on Fabry-Perot etalons applied to a 100 MHz Er-doped fiber optical frequency comb working at 1560 nm to increase its repetition frequency. A Fabry-Perot cavity is constructed based on a transportable cage system with two silver mirrors in plano-concave geometry including the...journal article 2016
