Congratulations to Alex Spott and colleagues for a postdeadline paper at the 2017 IEEE International Photonics Conference on the first Interband Cascade Laser on Silicon. October 12, 2017 Alexander Spott

We demonstrate the first interband cascade lasers heterogeneously integrated with silicon waveguides. The 3.6 μm wavelength lasers operate in pulsed mode at room temperature, with threshold currents as low as 394 mA.

High efficiency low threshold current 1.3 μm InAs quantum dot lasers on on-axis (001) GaP/Si September 27, 2017 High efficiency low threshold current 1.3 μm InAs quantum dot lasers on on-axis (001) GaP/Si

As a result of record low threading dislocation densities, the threshold current and threshold current density have gone down in our Quantum Dot lasers, and we see record high wallplug efficiencies for any laser on silicon.

The cover of the latest issue of Optica shows the latest quantum dot microring lasers on silicon with record low lasing thresholds.  This is promising for next generation data center interconnects.

The Revolution Has Just Begun: Q&A with John Bowers January 8, 2017 Image of Dr. Bowers

UCSB successfully demonstrated an electrically pumped hybrid silicon laser a decade ago. That advance has paved the way for the commercial production of high-bandwidth silicon photonic devices. Today, Bowers is leading UC Santa Barbara’s Institute for Energy Efficiency’s involvement in the AIM initiative and is a central figure in this exciting field. Photonics Spectra spoke with Bowers about AIM, his breakthrough work and the impact of integrated photonics on medicine, communications and…
