Integrated-optics-based swept-source optical coherence tomography

Optics Letters, 2012
We designed, fabricated, and characterized an integrated-optics-based swept-source optical coherence tomography (SS-OCT) system in TriPleX technology. An external 1300 nm swept source is coupled to the chip, which contains waveguide structures for interferometric depth ranging and balanced detection.

Swept-Source Optical Coherence Tomography

2016
In the two decades since optical coherence tomography (OCT) was first described (Huang et al. 1991), this technology has played essential roles in ophthalmology as well as other branches of medicine. The technology has been adapted to produce noninvasive, high-resolution images of both the anterior segment (cornea and structures at the angles) and ...
