TL;DR: In this article, a portable biosensor microsystem consisting of 20 micromechanical cantilevers produced in silicon technology, a polymer microfluidic system for delivery of the samples, an array of 20 vertical cavity surface emitting lasers (VCSELs) with collimated beams thanks to an integrated microlens array, an optical coupling element to provide the optical path required, and chips with the photodetectors and the CMOS circuitry for signal acquisition and conditioning, capable of measuring the cantilever deflection with sub-nanometer resolution.

TL;DR: In this article, a near-field sensor using the optical feedback properties of a vertical cavity surface-emitting laser (VCSEL) as the detection principle is proposed and demonstrated based on the monitoring perturbation induced in the laser cavity by the backscattered light coming from the specimen.

TL;DR: In this paper, a simple and novel design for power monitoring, integrated in a VCSEL, is presented, which enables delivery of a photocurrent of several hundred µA from the lateral emitted light, throughout the whole light-current characteristics.

TL;DR: In this paper, a vertical-cavity surface-emitting laser (VCSEL) was used as a resonant-Cavity-enhanced detector for dual-purpose application.

TL;DR: In this article, the authors investigated a simpler solution based on a standard VCSEL array, using in plane optical waveguiding of spontaneous emission in the intrinsic central zone of the devices.
