Santec Announce a Record Wavelength Scan for an Electrically Pumped VCSEL

KOMAKI, Aichi, January 9, 2019,- Santec Corporation (JASDAQ: 6777) Santec, a leading manufacturer of tunable lasers, optical instruments, and fiber-optic components, announces a record 88nm wide continuous wavelength scan for an electrically pumped VCSEL (Vertical Cavity Surface Emitting Laser) light source. This performance record for a 1050nm centered VCSEL is a result of a collaborative effort between Santec, Tokyo Institute of Technology and Tokyo University’s Institute of Industrial Science. This result will be reported at the upcoming Photonics West 2019 meeting in San Francisco [1].

The High-speed Scanning Tunable VCSEL’s element is made up of two parts; the VCSEL, responsible for laser oscillation, and optical MEMS, (Micro Electro Mechanical System) responsible for high speed scanning. The project was brought to fruition thanks to VCSEL research carried out by Tokyo Institute of Technology’s associate professor Nobuhito Nishiyama and optical MEMS research completed with Tokyo University’s Institute of Industrial Science’s professor Hiroshi Toshiyoshi. Using an electronically pumped VCSEL to achieve such a wide scanning range typically proves to be a difficult task, but the combined research efforts produced designs that not only extends the scanning range to 88nm, but also preserve the reliability typically associated with electronically pumped sources.

Santec have applied this breakthrough in electrically pumped tunable VCSEL technology to release a new version of the HSL-1 tunable VCSEL product.

The details will be reported at the conference of BiOS/Photonics West 2019 (February 2-4, 2019) in San Francisco, USA[1]. And the product (HSL-1 VCSEL) will be exhibited at santec booth (booth #8762 / #762) of the conference exhibition.

Performance Highlights

  • Wide scanning range
    An 88nm scanning range around 1050nm is ideal for high resolution imaging in medical (even demanding ophthalmic applications), production inspection, and 3D-sensing applications.
  • Long Coherence Length
    Over 100 meters of coherence length. The increased coherence length makes the HSL-1 attractive for 3D sensing applications including coherent LiDAR
  • Selectable scan speeds
    The scan speed of HSL-1 can be user defined up to 200-kHz and reconfigured after shipping for enhanced flexibility in customer product configuration.
