Tyco Electronics’ TO-56 Laser
is an InGaAsP/InP-based Strained
Multi-Quantum Well (SMQW)
device that provides stable, single
transverse mode oscillation with
emission wavelength of 1310nm.
The Laser packages are
uncooled, hermetically sealed
for high reliability and incorporate
a photodiode for monitoring
optical output.
