Optical gain of 11 db/cm has been achieved at 1.3microns in InP:Fe by photorefractive two-wave mixing. The insertion loss is 0.7 db for a 9mm long crystal.

The enormous traffic growth sets a stringent requirement to upgrade short-reach optical links to 1.6 TbE capacity in an economically viable way.

We proposed and demonstrated a symmetrical 40-Gbps time division multiplexed passive optical network (TDM-PON) using low-cost 10-Gbps optical components in the optical network unit, optical amplifi

Summary form only given, as follows. The optical amplifier is a key element in optical communication networks.

While fiber amplifiers have important advantages over semiconductor amplifiers for discrete applications, the potential to integrate the latter with other active and passive components to build com

We present a structural and optical characterization of scepterlike micrometer-sized free-standing structures, composed of a long InGaP rod with a metallic sphere on its top, grown on polycrystalli

The authors report that anisotropic confining potentials in laterally coupled semiconductor quantum dots (QDs) have large impacts in optical transitions and energies of intershell collective electr

Bandgap optical recombination from the two-dimensional electron gas in GaAS-(AlGa)As quantum wells was measured in the regime of the fractional quantum Hall effect.

An optical antenna based nanoLED design that enhances photoluminescence of a semiconductor emitter by more than 10× is presented.

Atoms and molecules are too small to act as efficient antennas for their own emission wavelengths.
