Micro-optics for optical interconnects

Optical interconnects offer high speed and parallelism for efficient data c ommunication within future electronic computers. This applies even for inte rconnects over short distances, such as in inter- and intrachip communicati on. Miniaturization and integration of optics are mandatory for an effectiv e merger of optical and electronic functionalities. This paper gives an ove rview of recent developments in fabrication techniques for micro-optical co mponents and describes different types of system architectures, based on pr inciples like guided wave optics, diffractive and refractive free space opt ics and hybrid forms.
