“…However, their beam divergence is relatively high (10 to 22°). As a result, a direct insertion of such sources in a compact system is not possible without the use of an integrated microoptical element such as a refractive microlens [2]. Furthermore, a dynamic control of the position and the size of laser beam is more and more in demand for such systems [3] [4].…”

We report on design and fabrication of a VCSELbased Micro-Optical-Electrical-Mechanical-System (MOEMS) suited for portable optical biosensors. It is based on a tunable polymer microlens directly integrated on the surface of the VCSEL laser device. We demonstrate that this method leads to a VCSEL focusing at a working distance of ~300µm suitable for optical analysis in a microfluidic channel. Moreover, as the microlens can be vertically moved up to 8µm with an applied power of only 43 mW (3V), a dynamic scan of the laser spot is possible over 100µm. This integrated approach opens new insights for the use of VCSEL arrays in miniaturized optical sensors.

“…The improved beam divergence angle (full angle at half maximum intensity) is 74 , which is about 3-4 times the value of VCSELs with a much larger aperture diameter on the order of microns. 31 Though this divergence is still too large for direct implementation in certain practical on-chip applications and on-chip microlens will be required for collimation or focusing, 32 we think improved beam quality may help to relieve requirements on such micro-optics needed. The height of the tapered region in this simulation is h ¼ 700 nm and its sidewall tilting angle is 20 .…”

We demonstrated for the first time an azimuthally polarized laser source from an electrically driven metallic cavity nanolaser with a physical cavity volume of 0.146 λ3 (λ = 1416 nm). Single TE01 mode lasing at 78 K was achieved by taking the advantages of the large free spectral range in such nanoscale lasers and the azimuthal polarization of lasing emission was verified experimentally. Mode shift controlled by device cavity radius was observed over a large wavelength range from 1.37 μm to 1.53 μm. Such metallic cavity nanolaser provides a compact electrically driven laser source for azimuthally polarized beam.
