چکیده

A hybrid micro-macro-optical shuffle interconnection approach is described. The new concept minimizes distortion in multichip smart-pixel shuffle interconnection systems that use macro-optics to link dense arrays of vertical-cavity surface-emitting laser (VCSEL) sources and matching arrays of detectors. The typical narrow-beam cones of VCSEL's are exploited by use of beam-deflecting micro-optics to create an optical system that is symmetric about its aperture. Since symmetric systems are well known to cancel distortion, this novel concept provides the means to achieve the required high degree of interchip registration accuracy.

Analysis of a hybrid micro/macro-optical method for distortion removal in free-space optical interconnections.

Eikonal analyses are applied to a hybrid micro/macro-optical shuffle interconnection approach that minimizes distortion in a multichip smart-pixel shuffle interconnection system. The optical system uses off-axis imaging elements to link clusters of dense arrays of vertical-cavity surface-emitting laser (VCSEL) sources to matching clusters within arrays of detectors. A critical requirement for s...

Experimental validation of hybrid micro-macro optical method for distortion removal in multi-chip global free-space optical-interconnection systems.

Experimental validation of a distortion removal technique for multi-chip free-space optical shuffle interconnections is presented. The free-space fabric links dense two-dimensional arrays of vertical cavity surface emitting laser(s) (VCSEL)(s) and detectors and must achieve full field registration on the order of 10 microns across the entire array. The new hybrid micro-macro optical concept rea...

Permutation routing in optical MIN with minimum number of stages

In hybrid optical Multistage Interconnection Networks (MIN’s), optical signals are routed by electronically controlled switches using directional couplers. One important problem of these hybrid optical MIN’s is the path-dependent loss of the optical signal, which is directly proportional to the number of couplers, i.e., the number of switches through which the signal passes. In general, given t...

AdOpt: analog VLSI stochastic optimization for adaptive optics

Phase distortion in wavefront propagation is one of the key problems in optical imaging and laser optics applications. We present a hybrid VLSI and optical system for real-time adaptive phase distortion compensation. The system operates “model-free”, independent of the specifics of the distorting optical medium and the compensation control elements. Our VLSI system implements stochastic paralle...

Multi-Cell Switch-Mode Power Amplifier with Closed-Loop Hybrid Output Voltage Filter

Abstract In this paper a promising novel output voltage filtering concept for multi-cell switch-mode power amplifiers is analyzed. The proposed hybrid filtering concept is based on a passive LC filter enhanced by a linear-mode correction stage of small rated power. Using this principle, also "sub-harmonic" (i.e. low-frequency) switching noise distortions (typically appearing in real interleaved...
