A cryogenic packaged vertical-cavity-surface-emitting laser (VCSEL) with microwave input and coupled OM4 fiber for optical output was developed demonstrated operation from 295 to 2.9 K. Record K data links of 100 Gbps pulsed amplitude modulation 4-level have been an energy per bit ∼153.4 fJ/bit when TDECQ = 3.79 dB. The energy/bit is limited by the link path bandwidth resulted cable loss VCSEL ...

The ability to fabricate monolithic two-dimensional (2D) diode laser arrays is a key step towards making high-power lasers at low cost, because the manufacture of such laser arrays eliminates labour-intensive fabrication and packaging [ 11. The surface-normal topology of the vertical cavity surface-emitting laser (VCSEL) makes it ideally suited to the formation of 2D arrays for high power appli...

Dissipative solitons are self-localized states which can exist anywhere in a system with translational symmetry, but in real systems this translational symmetry is usually broken due to parasitic inhomogeneities leading to spatial disorder, pinning the soliton positions. We discuss the effects of semiconductor growth induced spatial disorder on the operation of a cavity soliton laser based on a...

An implementation of a highly efficient spatiotemporal vertical-cavity surface-emitting laser (VCSEL) model in the circuit simulation environment of Cadence is presented. The VCSEL model, based on a set of modified rate equations, is written in Verilog-A. It enables the association of the VCSEL model with transistor-level models of the driver and detector circuits. Furthermore, the spatiotempor...

In this Letter, we present Fourier-transform-limited, nanosecond scale optical pulses from a vertical cavity surface emitting laser (VCSEL) using injection locking with narrow-band seed laser. We examine two different injection-locking architectures and show that can achieve an effective range of over 8 GHz extinction ratio 20,000:1. These results indicate injection-locked VCSELs could become k...

We propose a new set of equations describing a cylindrical vertical cavity surface emitting laser (VCSEL) cavity under CW operation, based on the rate equations including lateral carrier diffusion. The only numerical step in the calculation consists in finding the roots of a polynomial expression. This model enables a quasi-instantaneous calculation of the laser’s light-current characteristic, ...

We report a cost-effective transmitter optical sub-assembly using a monolithic four-wavelength vertical-cavity surface-emitting laser (VCSEL) array with 100-GHz wavelength spacing for future-proof mobile fronthaul transport using the data rate of common public radio interface option 6. The wavelength spacing is achieved using selectively etched cavity control layers and fine current adjustment....

The control of lateral mode operation using a photonic crystal in a vertical-cavity surface-emitting laser ~VCSEL! is analyzed and confirmed experimentally. By controlling design parameters of the photonic crystal pattern, we have produced photonic crystal VCSELs that operate in higher order defect modes in addition to the fundamental defect mode. The transverse modal behavior is consistent wit...

Vertical-Cavity Surface-Emitting Laser (VCSEL) is a type of semiconductor laser with laser beam perpendicular to the surface of the semiconductor substrate, as shown in Fig.1(a) [1]. VCSEL has many advantages, such as non-divergence output beam, fabrication and test on wafer, easy two-dimensional integration, and single longitudinal mode work. VCSEL is composed of an active region sandwiched be...
