VCSEL arrays in self-interferometry arrangement have the potential to be low cost imaging tool for blood perfusion . The goal of the Action BM1205 is to develop an ultra-compact sensing technology based on the selfmixing interferometer that uses Vertical-Cavity Surface-Emitting Laser (VCSEL) arrays both for the emission and the detection of light. This technique has high sensitivity, high signa...

Electrical IO is becoming limited by copper interconnect channel losses that depend on frequency and distance. Package-to-package optical interconnects see negligible frequency-dependent channel losses, but data rates are limited by the intrinsic optical dynamics and electrical parasitics of the optical devices. This thesis presents 90nm CMOS front-end circuits which apply techniques to operate...

The design of a biwavelength transceiver (TRx) module for parallel simultaneous bidirectional optical interconnects is described. The TRx module has been implemented using two different wavelengths, 850 and 1060 nm, to send and receive signals simultaneously through a common optical interface while optimizing cost and performance. Filtering mirrors are formed in the optical fibers which are emb...

This paper discusses the design and the internal device physics of novel high-performance vertical-cavity surfaceemitting lasers (VCSELs) emitting at 1.32 μm wavelength. Our VCSEL design features intra-cavity ring contacts, strain-compensated AlGaInAs quantum wells, and an AlInAs/InP tunnel junction. The tunnel junction is laterally confined forming an aperture for current injection and wave gu...

Optical manipulation of cells and particles is an efficient non-destructive technique for isolation and sorting in the field of biophotonics. For several years, vertical-cavity surfaceemitting lasers (VCSELs) have been investigated as light sources for particle manipulation inside microfluidic channels, where their small dimension and low power consumption enable direct integration with the cha...
