Use of optical traps for the manipulation of biological particles was recently proposed, and initial observations of laser trapping of bacteria and viruses were reported with visible argon laser li
Optical trapping and manipulation of tobacco-mosaic viruses and motile bacteria by the radiation pressure forces of laser light were demonstrated using single-beam gradient traps.
In a new transmission format the output of a 10 Gb/s convolutional FEC encoder is directly mapped on an optical 10 Gbaud DQPSK signal.
Continued scaling of silicon CMOS technologies to smaller feature sizes will provide impressive opportunities for integration of very complex processing systems on single IC's and single wafers.
We have discovered phonons active in resonant Raman scattering from GaAs quantum well heterostructures that are actually the optical vibrations of thin ionic slab.
With a recently developed semiconductor heterostructure it has become possible to tune continuously the electron density in multiple quantum wells.
Optical waveguides with metal cladding are important for a number of applications. However, metal cladding causes undesirable optical waveguide loss.
Disaggregated optical technologies have the potential to provide cost-effective and vendor-neutral optical node solutions especially suitable for metro networks.
Tomlinson-Harashima precoding is applied to transmit 92 GBd PAM-4 signal over 2-km SMF using 80 Gsa/s DAC/ADC together with an optical-amplifier-free intensity modulation direct detection (IM/DD) s
Optical-feedback cavity-enhanced absorption spectroscopy is demonstrated in the mid-IR by using a quantum cascade laser (emitting at 4.46 mu m).
