Introduction
- theory paper motivation by Andre xuereb.
- Interesting parameter regime towards enhanced OM
- state of the art: Dantan's bare membranes; Heidmann's high reflectivity PhCs; trampolines with potentially high mechanical Q;
- Two highly reflective membranes - PhC tethered membranes
Content
- PhC tethered membranes: optical and mechanical characterization
- Array of 2 membranes: optical characterization: PhC resonances, overlapping resonances, features of transmission spectra: FSR, Finesse (R1, R2)
- Modelling with TMM and fabry-perot-etalon formula consisting of only mirror reflectivities
Selling points
- integrated two membrane array that meets the requirements for showing enhanced OM coupling in the transmissive regime
- Reflectivity greater than 99.x %, with decent mechanical quality factors (if necessary)
- Compare Qf as well (but lower as what can be achieved, as fabricated on 200nm nitride layers), but now with high reflectivity
- No tip tilt alignment between two individual membranes from different wafers
- Silicon/Silicon-Nitride platform well known fabrication techniques
