  • Silicon Photonics Vertical Cavity Surface Emitting Laser for Island Applications

    Silicon Photonics Vertical Cavity Surface Emitting Laser for Island Applications

    In this paper, we present the development and performance of a 940nm multimode VCSEL with 3-dB small-signal modulation bandwidth exceeding 25GHz over temperature and relative intensity noise (RIN) below -145dB/Hz, suitable for 100Gb/s per lane data transmission. The VCSEL's 940nm center wavelength. What are Vertical Cavity Surface-emitting Lasers? VCSELs are semiconductor lasers, more specifically laser diodes with a monolithic laser resonator, where the emitted light leaves the device in a direction perpendicular to the chip surface. These include: These features make VCSELs better suited to a wide range of applications than conventional edge-emitting diode lasers and LEDs.


  • Applications and Functions of Fiber Optic Sensors

    Applications and Functions of Fiber Optic Sensors

    Optical fibers can be used as sensors to measure, , and other quantities by modifying a fiber so that the quantity to be measured modulates the,,, or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required. A particularly useful feature of intrinsic fiber-optic sensors is that they can, if required, provide distributed sensing over very large distances.
