Integrated Al2O3: Er³⁺ DFB laser for temperature control free operation with silicon nitride ring filter

We demonstrate almost synchronized temperature dependent wavelength shift of Al2O3:Er3+ DFB laser (2.57 GHz/°C) and Si3N4 ring filter (2.47 GHz/°C), which makes it possible for on-chip transceiver operation without temperature control. CLEO:2014 © 2014 OSA.
