The focusing grating coupler (FGC) can be constructed using holographic techniques. Due to the wavelength scaling between the construction of the FGC and its final enduse operation, aberrations exist in the final spot...

At present, whether the economic benefit of a designed optical system is high is an important mark to judge the opticaldesign level. The "Information - Price Ratio", the ratio of the spatial information qua...

A novel bipolar avalanche transistor is proposed. Controlled avalanche and large current output over a significant bias region is achieved by incorporating a staircase multiplication region at the base-collector junction. The iii-V materials choice, device design, and computed output characteristics are presented and discussed.
In this paper a design study is described for telescopes to be used in precision astrometry. Specifically, the application is the search for planets outside the solar system. The requirements are stringent because of ...

An alternative to Damped Least Squares (DLS) optimization of lens systems is described that involves Generalized Simulated Annealing (GSA) techniques in conjunction with DLS. The resultant method can often overcome lo...
