Alignment Tolerant Couplers for Silicon Photonics

Abstract: Laser integration, optical coupling and assembly are challenging problems that need to be further addressed to reduce the manufacturing costs of silicon photonics based products. In this paper, we propose novel coupling devices that facilitate the passive assembly of

Epitaxially grown vertical junction phase shifters for improved modulation efficiency in silicon depletion-type modulators

Abstract: High-speed silicon modulators based on the plasma effect in reverse-biased p(i)n junction phase shifters have been extensively investigated. The main challenge for such modulators is to maximize their modulation efficiency without compromising high-speed performance and insertion losses. Here, we
