Silicon sub-wavelength grating based scalable selective higher order mode pass filter for dual-band operation Open
In this work, two mode pass filters (MPF) have been demonstrated using silicon sub-wavelength grating (SSWG) structures to selectively pass TE 1 and TE 2 modes for dual-band operation (O-band and C-band). These MPFs utilize waveguides embe…

On-chip dual-band higher order mode pass filter using silicon subwavelength grating Open
In mode division multiplexing (MDM) technology multi-band higher order mode (HOM) pass filters are rarely introduced. However, these filters will support the MDM technology to be universal for all available wavelength bands used in fiber o…

Angled Flip-Chip Integration of VCSELs on Silicon Photonic Integrated Circuits Open
An investigation of angled flip-chip integration of a singlemode 850 nm vertical-cavity surface-emitting laser (VCSEL) on a silicon nitride photonic integrated circuit (PIC) is presented. Using numerical FDTD simulations, we consider the c…

VCSEL Wavelength Setting by Intra-Cavity Phase Tuning — Numerical Analysis and Experimental Verification Open
Monolithic multi-wavelength VCSEL arrays, with wavelengths of individual VCSELs precisely set in a post-epitaxial growth process, would enable compact multi-color light sources and transmitters for various sensing and datacom applications.…

High-power single transverse and polarization mode VCSEL for silicon photonics integration Open
We demonstrate a 6.5 mW single transverse and polarization mode GaAs-based oxide-confined VCSEL at 850 nm. High power is enabled by a relatively large oxide aperture and an epitaxial design for low resistance, low optical loss, and high sl…

VCSEL Techniques for Wavelength-Multiplexed Optical Interconnects Open
The majority of global data communication is taking place within data centers where data is stored and processed and where the largest part of the power used for global networking is consumed. With the rapidly increasing use of Internet-ba…
