Design and implementation of a trans-impedance amplifier for a miniaturized saturated absorption spectrometer.
(IEEE, 2021)
This paper presents the design, manufacture, and testing of a trans-impedance amplifier for a miniaturized saturated absorption spectrometer. The amplifier has a bandwidth of 32 kHz, a dc gain of 80.3 dB-Ohm, and an output ...
Synthesis of optical filters using microring resonators with ultra-large FSR
(12/06/2010)
We propose a novel synthesis method for designing flexible, tunable non-periodic filters. It is based on a building block which is presented by first time for these purposes, being the poles position tuned by means of a ...

Thermal tunability of photonic bandgaps in photonic crystal fibers selectively filled with nematic liquid crystal
(2010-12-01)
We address the bandgap effect and the thermo-optical response of high-index liquid crystal (LC) infiltrated in photonic crystal fibers (PCF) and in hybrid photonic crystal fibers (HPCF). The PCF and HPCF consist of solid-core ...

Design of an optical beam combiner for dual-frequency observation with ALMA
(ISSTT, 2017)
The aim of this work is to improve high-frequency calibration data on longbaseline observations for the ALMA antennas. A dual-frequency atmospheric phase error calibration method is proposedand will be ...

CNC control of a laser cutting machine
(IEEE, 1994)
This article describes the design and construction of a low power laser cutting machine with three degrees of freedom for applications such as wood, textile fabrics and the like. An available 10 Watt laser gun is used to ...
