BioPhotonics Issue: January The best proof that nature is art Researchers who study plant or animal organisms can, at any time, be witness to amazing sights when they place their subjects under the objective of a light microscope. Whether they view muscle cells or mussel shells, scientists with an eye for the artistic can capture wondrous images that delight the senses while.

      SS-OCT prototypes incorporating vertical cavity surface emitting lasers (VCSEL) as a light source have an even greater depth range of up to mm, greater than the axial length of the eye. Therefore, with VCSEL it is possible to image both anterior and posterior segments concurrently and without the need for additional attachments [3].

In this work the design and initial fabrication results are reported for the components of a compact optical-MEMS laser scanning system.

This system integrates a silicon MEMS laser scanner, a Vertical Cavity Surface Emitting Laser (VCSEL) and passive optical components. The MEMS scanner and VCSEL Cited by: 5. The wavelength tuning range of a tunable vertical-cavity surface-emitting laser (VCSEL) is strongly influenced by the design of the interface between the semiconductor cavity and the air cavity.

A single-mode continuous tuning range of 76 nm is realized using a bulk-micromachined vertical-cavity surface-emitting laser (VCSEL) operating at wavelengths around mum.

The first class of very rapidly wavelength tunable OCT lasers are vertical-cavity surface-emitting lasers (VCSELs) with a microelectromechanical system (MEMS) mirror.

They are based on a Fabry-Pérot resonator with tunable cavity length, and the semiconductor quantum well laser gain medium is located inside the by: Abstract. Microelectromechanical systems (MEMS) technology enables the creation of micro-optical elements that are inherently suited to cost-effective manufacturability and scalability because the processes are derived from the very mature semiconductor microfabrication by: 4.

The compact design is based on mounting the MEMS module and a vertical cavity surface emitting laser (VCSEL) onto a fused silica substrate that contains the rest of the optical system.

The estimated scan range of the system is {+-}4{degree} with a spot size of by: 7. Benjamin M. Potsaid.

KEYWORDS: Microelectromechanical systems, Mirrors, Optical amplifiers, Optical coherence tomography, Dielectrics, Reliability, Wavelength tuning, Vertical cavity. This miniature dispersive laser has been shown to yield narrow-linewidth emission tunable for over a nm range in the near infrared.

A second approach tunes an integrated vertical-cavity surface-emitting laser (VCSEL) that varies its wavelength by changing the length of the cavity (Kner et al., ). The length of the cavity is changed by.

A recent addition to the SOA family is the vertical-cavity SOA (VCSOA). These devices are similar in structure to, and share many features with, vertical-cavity surface-emitting lasers.

The major difference when comparing VCSOAs and VCSELs is the reduced mirror reflectivity used in. Wide and continuous wavelength tuning in a vertical-cavity surface- emitting laser using a micromachined deformable-membrane mirror M.C. Larson, J.S. Harris, Jr. (Applied Physics Letters ).
