We investigated hybrid-integration of InP semiconductor optical amplifier on silicon photonics chip using flip-chip bonding, and achieved in-line optical amplification of 10 dB. Silicon 1×8 splitter and selector are fabricated and operated with on-chip loss-compensation.
We present a polarization-diversity 4 $\times$ 4 optical switch composed of silicon-wire waveguides. The proposed 4 $\times$ 4 switch does not require a polarization rotator, which enforces a modification in a standard complementary metal–oxide–semiconductor (CMOS) process to achieve vertical asymmetry. The switch is fabricated on a 300-mm silicon-on-insulator (SOI) wafer with argon fluoride (ArF)...
Optics has the potential to solve some of the most exciting problems in information systems. It promises crosstalk-free interconnects with essentially unlimited bandwidth, long-distance data transmission without skew and without power- and time-consuming regeneration, miniaturization, parallelism, and efficient implementation of important algorithms such as Fourier transforms. Numerous information...
This paper explores the role of nanotechnology with special focus on nanophotonics in inhomogeneous metamaterials with applications for optical information and signal processing, communications, sensing, and health care.
Using a heterodyne nearfield scanning optical microscope (H-NSOM) we characterize the operation of a novel graded-index slab lens made of subwavelength features. Measured amplitude and phase distributions show light focusing and is used to learn about the device performance.
