The Schottky diode (named after German physicist Walter H. Schottky; also known as hot carrier diode) is a semiconductor diode with a low forward voltage drop and a very fast switching action.. The tunable laser could be set to any desired wavelength either in the factory or in the field by a software command.. The performance parameters are:. Power. Spurious mode suppression.
