Signal optimization is affected during radio links between a transmitter and a receiver located in adjacent material media with differing optical densities. The optimization is carried out via the automated control theory method. The radio signal obtained after the optimization is coordinated with the two media's electrical characteristics simultaneously; and this enables low power and small an...
In this paper, after a brief overview on laser warning system (LWS), a new structure for an optical array that is used in its optical subsystem is introduced. According to the laser threats’ wavelengths (0.5 – 1.6 µm) and our desirable field of view (FOV), we used 6 lenses for gathering the incident radiation and then optimized the optical array. Lenses’ radius, their se...
An essential parameter in determining the system power budget in an optical transmission system is optical receiver sensitivity, defined as the minimum average optical power for a given bit-error rate (BER). When designing a good optical receiver, it is critical to understand the different parameters that will impair overall receiver sensitivity. This article provides an indepth analysis of com...
We present a fully integrated 12.5-Gb/s optical receiver fabricated with standard 0.13-µm complementary metal-oxide-semiconductor (CMOS) technology for 850-nm optical interconnect applications. Our integrated optical receiver includes a newly proposed CMOS-compatible spatially-modulated avalanche photodetector, which provides larger photodetection bandwidth than previously reported CMOS-compati...
We present a 12.5-Gb/s monolithically integrated optical receiver with CMOS avalanche photodetector (CMOS-APD) realized in 65-nm CMOS technology. The optical detection bandwidth limitation of CMOS-APD due to the carrier transit time is compensated by underdamped TIA. With this optical receiver, 12.5-Gb/s 850-nm optical data are successfully detected with bit-error rate less than 10 at the incid...
We propose a super-channel flexible wavelength division multiplexing (WDM) receiver architecture. The receiver, which requires no optical filtering, only a pair (I and Q phases) of coherent optical detectors, and an electrical receiver system, can simultaneously recover multiple wavelength-multiplexed channels using cascaded optical and electrical down-conversion. The receiver data capacity inc...
In this work, we report an optical receiver with integrated photodiodes operating at 850nm wavelength. The receiver achieves a data-rate of 2.5Gb/s without using any equalizer. To minimize the area, no inductors are used in the design. The entire receiver occupies an area of O.38mm2• This represents the smallest optical receiver operating at the Gb/s regime. The chip is fabricated in O.18J.lm C...
