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.

An experimental observation of power and wavelength optical bistability and nonlinear gain in a 1550nm vertical-cavity semiconductor optical amplifier (VCSOA) operated in reflection and biased above and below threshold is reported. Two distinct types of optical bistability, clockwise and anticlockwise, are observed.
