Phase and alignment noise in grating interferometers
A. Freise, A. Bunkowski, R. Schnabel
Diffraction gratings have been proposed as core optical elements in future laser-interferometric gravitational-wave detectors. In this paper we derive equations for the coupling be…
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…
Diffractive Optics for Gravitational Wave Detectors
A. Bunkowski, O. Burmeister, K. Danzmann +4
All-reflective interferometry based on nano-structured diffraction gratings offers new possibilities for gravitational wave detection. We investigate an all-reflective Fabry-Perot…
Low-loss grating for coupling to a high-finesse cavity
A. Bunkowski, O. Burmeister, P. Beyersdorf +5
A concept for a low loss all-reflective cavity coupler is experimentally demonstrated at a wavelength of 1064 nm. A 1450 nm period dielectric reflection grating with a diffraction…
