A 20-km/60-Gb/s Two-Way PON Based on Directly Modulated Two-Stage Injection-Locked 1.55- $\mu\hbox{m}$ VCSEL Transmitters and Negative Dispersion Fibers

IEEE Photonics Journal, 2015
A 20-km/60-Gb/s two-way passive optical network (PON) based on directly modulated two-stage injection-locked 1.55-μm vertical-cavity surface-emitting laser (VCSEL) transmitters and negative dispersion fibers (NDFs) is proposed and demonstrated.

VCSELs resurgent

III-Vs Review, 2004
Whatever the viewpoint on the state of play in the telecom/datacom marketplace, it is undeniably the case that the VCSEL is here to stay. Moreover, the potential of this laser diode family is only beginning to be exploited. Much will depend on factors such as materials and device technology, applications and competition in the market from other laser ...

Vcsel structure

, 2015
The invention relates to a VCSEL structure based on a novel grating reflector. The grating reflector comprises a grating layer with a contiguous core grating region having a grating structure, wherein an index of refraction of high-index sections of the grating structure is at least 2.5, and wherein an index of refraction of low-index sections of the ...

Enhanced polarization locking in VCSELs

Applied Physics Letters
While optical injection locking (OIL) of vertical-cavity surface-emitting lasers (VCSELs) has been widely studied in the past, the polarization dynamics of OIL have received far less attention. Recent studies suggest that polarization locking via OIL could enable novel computational applications such as polarization-encoded Ising computers.
