22-Gb/s Long Wavelength VCSELs.
1.55-microm vertical cavity surface-emitting low-parasitic lasers show open eyes up to 22-Gb/s modulation speed. Uncooled error-free operation over a wide temperature range up to 85 degrees C under constant bias conditions is demonstrated at 12.5-Gb/s data rate. At these fixed bias conditions the laser characteristics are practically invariant with temperature. These are the highest data-rates ...
متن کاملHigh-Speed InP-Based Long-Wavelength VCSELs
The rapid growth of internet and cloud computing applications drives a huge demand for bandwidth capacity in communication networks, while power consumption, cost, and space density must scale down. This growth leads to an increase in the size of data centers (longer optical links), and of the fibers’ channel data rate, rooted in Moore’s Law. Until now, multi-mode fibers (MMF) have been largely...
متن کاملShort-wavelength MEMS-tunable VCSELs.
We present electrically-injected MEMS-tunable vertical-cavity surface-emitting lasers with emission wavelengths below 800 nm. Operation in this wavelength range, near the oxygen A-band from 760-780 nm, is attractive for absorption-based optical gas sensing. These fully-monolithic devices are based on an oxide-aperture AlGaAs epitaxial structure and incorporate a suspended dielectric Bragg mirro...
متن کاملModeling light vs. current characteristics of long-wavelength VCSELs with various DBR materials
Long-wavelength vertical-cavity surface-emitting lasers (LW-VCSELs) are investigated using electro-thermal, optical, and electronic modeling. The strain-compensated InGaAsP multi-quantum-well active region of the device example is vertically sandwiched between various distributed Bragg reflectors (DBRs). InP/InGaAsP, Si/Si02, and GaAs/AlAs mirrors are considered as well as novel combinations li...
متن کاملInvestigating Scaling Effects on The Static Characteristics of Long-Wavelength Vertical Cavity Lasers (VCSELs)
In this paper, the characteristics of longwavelength vertical-cavity surface-emitting laser (VCSEL) lasing at 1550 nm have been studied based on the influence of the oxide aperture radius. Using the oxide confined VCSEL model, we examine the static operations taking into account the carrier-noise, photon-noise and phase-noise including feedback of the external cavity. From the simulation, sever...
