Silicon on Sapphire (SOS)
Silicon on sapphire (SOS) is a hetero-epitaxial process wherein a thin layer of silicon is 'grown” on a sapphire (Al2O3) wafer. SOS is part of the silicon on insulator (SOI) family of CMOS technologies. Silicon on sapphire is primarily used in military and space applications because of its inherent

piezoelectric transducers using CdS or ZnO, were first used in microwave delay lines as a means of generating the high frequency wide bandwidth time delays required by radar signal processing applications. These delay lines required piezoelectric plates bonded to the delay medium (which was often sapphire

The signal from a detector facing the laser provides information on the identity and concentration of the molecules present as the laser is tuned across the relevant absorption bands. Semiconductor lasers fabricated using epitaxially
