Congratulations to Justin Norman for winning Best Student Paper award at the 2017 IEEE International Photonics Conference October 24, 2017 Justin Norman
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.

1.3 μm submilliamp threshold quantum dot micro-lasers on Si August 1, 2017 Optica August 2017 cover

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…

Looking for Postdocs (immediately) and Graduate Students for Admission in Fall 2018 December 31, 2016 2.56 Tbps Network on Chip

We are looking for two photonics students and two postdocs for design, fabrication and testing of photonic integrated circuits. Students should apply to the ECE or Materials departments for Fall 2018 admission. Postdocs should apply directly to Prof. Bowers.
