hp-finite-elements for simulating electromagnetic fields in optical devices with rough textures
S. Burger, P. Gutsche, M. Hammerschmidt +5
The finite-element method is a preferred numerical method when electromagnetic fields at high accuracy are to be computed in nano-optics design. Here, we demonstrate a finite-eleme…
hp-finite element method for simulating light scattering from complex 3D structures
S. Burger, L. Zschiedrich, J. Pomplun +2
Methods for solving Maxwell's equations are integral part of optical metrology and computational lithography setups. Applications require accurate geometrical resolution, high nume…
6 W, 1 kHz linewidth, tunable continuous-wave near-infrared laser
Sheng-wey Chiow, Sven Herrmann, Holger Mueller +1
A modified Coherent 899-21 titanium sapphire laser is injection locked to produce 6-6.5 W of single-frequency light at 852 nm. After closed-loop amplitude control and frequency sta…
Nanosecond electro-optical switching with a repetition rate above 20MHz
Holger Mueller, Sheng-wey Chiow, Sven Herrmann +1
We describe an electro-optical switch based on a commercial electro-optic modulator (modified for high-speed operation) and a 340V pulser having a rise time of 2.2ns (at 250V). It…
