  2. 11. Processing technologies for long-wavelength vertical-cavity lasers

    Author : Fredrik Salomonsson; KTH; []
    Keywords : VCSEL; vertical-cavity laser; semiconductor laser; long-wavelength; DBR; oxidation; wafer fusion; InGaAs; semiconductor processing;

    Abstract : Vertical-cavity surface-emitting lasers (VCSELs) areattractive as potential inexpensive high-performance emittersfor fibre-optical communication systems. Their surface-normalemission together with the small dimensions are beneficial forlow-cost fabrication since it allows on-wafer testing,simplified packaging and effective fibre-coupling. READ MORE

  5. 13. Developments for Improved Performance Vertical-Cavity Surface Emitting Lasers

    Author : Xingang Yu; Mattias Hammar; Jens A. Tellefsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The vertical-cavity surface-emitting laser (VCSEL) is a type of laser diode that emits light from the surface of the chip from which it is manufactured rather than from a cleaved edge as so far has been common for most telecommunication lasers. VCSEL’s low cost, high power efficiency and low power consumption properties make it a very attractive signal source for many applications such as fiber optical communication, optical interconnects, 3D sensing, absorption spectroscopy, laser printing, etc. READ MORE

  6. 14. Controlling the Optical Properties of Vertical-Cavity Surface-Emitting Lasers

    Author : Josip Vukusic; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The insatiable demand for higher bandwidth in communication systems has led to the optical fiber trickling its way down to the consumer, gradually replacing the conventional copper cable. This trend is expected to continue, rendering these systems highly cost sensitive and therefore spurring the development of new breeds of semiconductor lasers, such as the vertical-cavity surface-emitting laser(VCSEL).
