Vixar Demonstrates Widely Tunable Single Mode VCSEL

Vixar has demonstrated a widely tunable laser platform based on integration of VCSEL and microelectromechanical system (MEMS). The new advancement is part of a NIH funded program to develop multiwavelength swept sources for tissue spectroscopy applications. The device combines a vertical cavity surface emitting laser with a thermally actuated movable mirror to tune the laser cavity across a wide spectral bandwidth. The unique design allows for mode-hop free continuous tuning with less than 2.5V applied bias. Single mode output power up to 0.75mW has been achieved over 32nm of tuning. The electrically pumped architecture and compact form factor (<0.5 mm square) enables straightforward operation and versatile packaging flexibility. Spectra below demonstrate a VCSEL centered at 935nm, however the approach can be adapted to any wavelength range from 660 nm to 1.1um for a variety of medical and industrial sensing applications.

 

The tunable VCSEL is still in development, but we welcome discussions with potential partners regarding applications and more specific requirements for the technology.

 

        

 

Vixar exhibiting at LASER World of PHOTONICS 2019

June 24th-27th, 2019: Vixar will be exhibiting at the LASER World of PHOTONICS to be held in Munich, Germany. Vixar designs, develops and manufactures visible and IR (670nm to 940nm) Vertical Cavity Surface Emitting Lasers (VCSELs) for consumer, industrial, automotive and medical applications.

Vixar can be found at Hall B3 Booth 103, along side the Laser 2000 GmbH team.

Products highlighted will include 4W 850nm and 940nm VCSEL arrays in surface mount packages including PLCC or ceramic with diffuser or DOE. We will also discuss how Vixar is improving power efficiency and beam quality for large power array VCSEL products.
