Understanding our future through Open Access research about our past...

Strathprints makes available scholarly Open Access content by researchers in the Centre for the Social History of Health & Healthcare (CSHHH), based within the School of Humanities, and considered Scotland's leading centre for the history of health and medicine.

Research at CSHHH explores the modern world since 1800 in locations as diverse as the UK, Asia, Africa, North America, and Europe. Areas of specialism include contraception and sexuality; family health and medical services; occupational health and medicine; disability; the history of psychiatry; conflict and warfare; and, drugs, pharmaceuticals and intoxicants.

Abstract

Tunable fiber lasers using using erbium-doped fiber amplifier (EDFA) and SOA were investigated for their wide wavelength tunable range, and potentially fast tuning speed. The spectral characteristics of lyot filter placed inline with the two amplifiers was also analyzed. The performance of EDFA and SOA was compared in a wavelength tunable fiber ring structure. Wide tuning ranges of 25 nm and 35 nm were achieved with a fiber ring laser using EDFA and SOA respectively. The laser using the SOA showed a broader wavelength tuning range and a stronger red shift to L-band.
