For more than ten years, the access network market is attracted by the Vertical-Cavity Surface-Emitting Lasers well known as the acronym VCSEL. Indeed, the numerous advantages of this component make the VCSEL technology suitable for access networks and today several studies have demonstrated the feasibility of various configurations of Optical Access Network (OAN) using the VCSEL Technology. Ab...

We report experimental evidence of spontaneous formation of localized structures in a 80 μm diameter Vertical-Cavity Surface-Emitting Laser (VCSEL) biased above the lasing threshold and under optical injection. Such localized structures are bistable with the injected beam power and the VCSEL current. We experimentally investigate the formation of localized structures for different detunings bet...

We have studied experimentally effects of two-frequency optical injection on a multimode vertical-cavity surface-emitting laser (VCSEL). The injected signal comes from another VCSEL. Polarization switching (PS) with and without frequency locking occurs for relatively small frequency detuning. Outside the regime of polarization switching, the VCSEL demonstrates two types of instabilities. The in...

We report the experimental demonstration of tunable ultraslow light using a 1.55 um vertical-cavity surface-emitting laser (VCSEL) at room temperature. By varying the bias current around lasing threshold, we achieve tunable delay of an intensity modulated signal input. Delays up to 100 ps are measured for a broadband signal with modulation frequency of 2.8 GHz. With a VCSEL design optimized for...

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...

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...

The first error-free data transmission beyond 1 km of multi-mode fiber at bit-rates exceeding 20 Gb/s is demonstrated using a high modulation bandwidth, quasi-single mode (SMSR~20 dB) 850 nm VCSEL. A VCSEL with small ~3 μm aperture shows quasi-single mode operation with a narrow spectral width. The top mirror reflectivity of the VCSEL is optimized for high speed and high output power by shallow...

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...

A 980 nm bottom-emitting vertical-cavity surface-emitting laser (VCSEL) with a p-contact diameter is reported to achieve high power and good beam quality. A numerical simulation is conducted on the current spreading in a VCSEL with oxidation between the active region and the p-type distributed Bragg reflector. It is found that, for a particular oxide aperture diameter, somewhat homogeneous curr...
