Ultrahigh transmission optical nanofibers

Optical Properties of GaSb Nanofibers

Amorphous GaSb nanofibers were obtained by ion beam irradiation of bulk GaSb single-crystal wafers, resulting in fibers with diameters of ~20 nm. The Raman spectra and photoluminescence (PL) of the ion irradiation-induced nanofibers before and after annealing were studied. Results show that the Raman intensity of the GaSb LO phonon mode decreased after ion beam irradiation as a result of the fo...

Capillary‐Force‐Assisted Optical Tuning of Coupled Plasmons

An ultrathin (few nanometer) polymer spacer layer is softened by local optical heating and restructured by strong capillary forces, which increase the gap between the plasmonic metal components. This results in a continuous blue-shift of the coupled plasmon from near infrared to visible with a tuning range of >150 nm that can be tightly controlled by adjusting either irradiation time or power.

2D parallel optical interconnects between CMOS ICs

The CMOS IC industry thrives on the down-scaling drive for ever smaller transistors, leading to faster, smaller and more complex digital systems. These ICs are interconnected by electrical tracks running on Printed Circuit Boards. Due to different frequency-dependent sources of signal degradation, the performance of these electrical interconnects lags behind the IC performance. As the electrica...
