Diffractively coupled Fabry-Perot resonator with power-recycling
Michael Britzger, Daniel Friedrich, Stefanie Kroker +6
We demonstrate the optical coupling of two cavities without light transmission through a substrate. Compared to a conventional coupling component, that is a partially transmissive…
Realization of a monolithic high-reflectivity cavity mirror from a single silicon crystal
Frank Brückner, Daniel Friedrich, Tina Clausnitzer +6
We report on the first experimental realization of a high-reflectivity cavity mirror that solely consists of a single silicon crystal. Since no material was added to the crystal, t…
All-reflective coupling of two optical cavities with 3-port diffraction gratings
Oliver Burmeister, Michael Britzger, André Thüring +4
The shot-noise limited sensitivity of Michelson-type laser interferometers with Fabry-Perot arm cavities can be increased by the so-called power-recycling technique. In such a sche…
Optical characterization of ultra-high diffraction efficiency gratings
A. Bunkowski, O. Burmeister, T. Clausnitzer +4
We report on the optical characterization of an ultra-high diffraction efficiency grating in 1st order Littrow configuration. The apparatus used was an optical cavity built from th…
Demonstration of 3-port grating phase relations
A. Bunkowski, O. Burmeister, K. Danzmann +1
We experimentally demonstrate the phase relations of 3-port gratings by investigating 3-port coupled Fabry-Perot cavities. Two different gratings which have the same 1st order diff…
Input-output relations for a 3-port grating coupled Fabry-Perot cavity
A. Bunkowski, O. Burmeister, K. Danzmann +1
We analyze an optical 3-port reflection grating by means of a scattering matrix formalism. Amplitude and phase relations between the 3 ports, i.e. the 3 orders of diffraction are d…
