Longitudinal Mode Selection via Bragg Gratings
A diffraction grating etched directly adjacent to the active semiconductor junction forces the laser into a singular longitudinal mode.
Peltier Thermal Precision within Hundredths of a Degree
Thermoelectric Peltier coolers stabilize diode junction temperatures within 0.01°C to lock center emission to dense WDM ITU grid channels.
Side-Mode Suppression Ratios Exceeding 45 dB
Side-mode suppression ratios (SMSR) exceeding 45 dB ensure crosstalk-free fiber optic communication over hundreds of kilometers.
