Zoom lens first-order search tools: Monte Carlo vs particle swarm optimization

Julie Bentley, Jacob Sacks

University of Rochester

It is often easier (and faster) for a lens designer to adapt an existing design or known design form to a new problem. Very rarely do you need to go back to first-order thin lenses and/or invent a new form. However, the design of a new zoom lens is complex and typically requires a designer to “start from scratch”. Monte-Carlo (MC) searches have proven to be an effective way to characterize the first order solution space of zoom lenses, but MC simulations can take many hours/days to be completed, slowing down the design process. Particle swarm optimization (PSO) is an alternative optimization algorithm that mimics the hunting or foraging behaviors of a group of organisms. This paper compares the sets of solutions generated by MC and PSO methods, showing that PSO is capable of generating a diverse set of solutions that typically outperform the solutions generated by MC in a fraction of the time.

Ray transfer matrix for onion-type GRIN lenses

We present the computation of an ABCD matrix for onion-type GRIN lenses. By applying a differential approximation of the layer thickness, the matrix product of a high number of matrices is synthetized into a single matrix where the elements are integrals. The difference between this ABCD matrix and a homogeneous lens matrix is one integration term in element C, which is the GRIN contribution to the lens power. In the case of the crystalline lens, the analytical approximation to the GRIN lens power provides an accurate and concise solution in terms of Gaussian hypergeometric functions.

Enabling photonic system integration by applying glass based microelectronic packaging approaches

Henning Schröder1, Wojciech Lewoczko-Adamczyk1, Daniel Weber2

1Fraunhofer IZM, Germany; 2Technische Universität Berlin

Advanced hybrid packaging technologies are used to enhance functionality of glass-based substrates featuring electrical, thermal and optical components including laser diodes, modulators, isolators, photonic integrated circuits, beam-splitters and micro lenses. Such glass-based substrates can be either thin glass layers on large panels containing optical waveguides or more mini-bench-like boards. Optical fiber interconnects, plugs, and electrical-optical integration platforms are used for higher level system integration. We discuss thin glass as a suitable base material for ion exchanged waveguide panels and interposers, precise glass structuring for posts and holders, electrical wiring and the related high precision assembly techniques.

Control of thermal emission for thermophotovoltaic systems

Thermal emitters play a key role in controlling the thermal radiation emitted in thermophotovoltaic systems and in increasing their energy conversion efficiency. Here, we present different designs of emitters with spectrally selective properties, based on easy-to-fabricate multilayer structures and characterized by a sharp transition from high to low emissivity in the region of interest. Those structures make use of refractory materials to allow working at high operating temperatures and they can be easily customized to maximize the thermal emission in the region of the desired wavelengths.

Removing microdefects on glass surfaces using laser radiation

Kerstin Götze1, Jens Bliedtner1, Jürgen Bischoff1, Oliver Faehnle2, Michael Kahl2

1University of Applied Sciences Jena, Germany; 2OST – Eastern Switzerland University of Applied Sciences

Scratches and microdefects on glass surfaces significantly impair the optical and mechanical properties of optical components. They already occur during mechanical processing (shaping) and have to be removed in several specific processing steps. A process is presented with which scratches and microdefects can be removed by means of CO2 laser radiation.
