A new type of integrated semiconductor laser that achieves ultrafast tuning and switching
Background Frequency tuning of laser sources in Photonic integrated circuits (PIC) has been based on thermal as well as current changes. Thermal-optic tuning is slow (kHz) and current sweep techniques lead to unwanted intensity modulation. PICs still lack ultra-fast frequency modulation and switching, an essential attribute for the wide adoption of...
