Vertical Cavity Surface Emitting Laser NRZ for Island Use
Because VCSELs emit from the top surface of the chip, they can be tested on-wafer, before they are cleaved into individual devices. This reduces the cost of the devices. It also allows VCSELs to be built not only in one-dimensional, but also in two-dimensional arrays. The larger output aperture of VCSELs, compared to most edge-emitting lasers, produces a lower divergence angle of the output beam, and makes possible high coupling efficiency with optical fibers.

Direct Modulation with Laser Diode
Modulating the output power of a laser diode can happen in two ways: by changing the signal input/driving current1,2 or by alternating the continuous wave output after the light is generated. 2 In laser modulation, the current or voltage varies with time to modulate the output signal from the laser. Laser modulation is a critical facet of laser technology, allowing for controlled variations in key parameters such as intensity, frequency, or phase. Such control opens the door to a broad range of scientific and commercial applications. Aerospace, automotive and biomedical industries all heavily. al electro-optic oracousto-optic modul ators.
