Integrated VCSEL Arrays for Optofluidic Sorting

We present the concept of an ultra-small, potentially low-cost microfluidic sorting unit based on vertical-cavity surface-emitting lasers. The densely packed lasers are integrated with the microfluidic channel and form an optical lattice. We show first results in an experimental setup, followed by tests of the first generation of integrated setups. A promising novel integration approach and fut...

Multiple-wavelength integrated photonic networks based on microring resonator devices

Microring resonator devices implemented on silicon and silicon-on-insulator substrates have a unique potential to be used in high-bandwidth multiplewavelength integrated photonic networks. A scheme for the wavelength allocation is proposed, and its feasibility is verified experimentally. The important system-level trade-offs that result from the proposed scheme, including those among bandwidth,...

Microscope-integrated Micromanipulator based on Multiple VCSEL Traps

The compactness of VCSELs (Vertical Cavity Surface Emitting Lasers) provides them the ability to meet the demands of current biochip technologies. In earlier research, optical trapping of live biological cells and microspheres based on VCSEL array has been realized in the form of parallel static traps on a translation stage. In microfluidic systems (lab-ona-chip devices), the background flow in...

Monolithically integrated multi-wavelength VCSEL arrays using high-contrast gratings.

We propose a novel design for multi-wavelength arrays of vertical cavity surface-emitting lasers (VCSELs) using high-contrast gratings (HCGs) as top mirrors. A range of VCSEL cavity wavelengths in excess of 100 nm is predicted by modifying only the period and duty-cycle of the high-contrast gratings, while leaving the epitaxial layer thickness unchanged. VCSEL arrays fabricated with this novel ...
