Abstract
40GSPS analog-to-digital converters (ADC) arerequired for realization of digital receivers up to 20GHz. An alloptical ADC is presented using an optical deflector for spatialsampling. The optimized design of optical deflector is based onoptical beam propagation and finite element modelingelectromagnetic modeling. An effective number of bits (ENOB) of6.6 ADC is achieved under a ±20V RF voltage swing and byminimalizing angular resolution with a leaky waveguide of 2cmlong. Design and implementation of a polymer waveguide arepresented, meeting the leaky waveguide coefficient of 0.1Np/cmand low optical attenuation with quality optical waveguidesurface flatness better than 20nm. A broadband (2 - 40GHz)transition from coplanar waveguide (CPW) to coupled microstrip(CMS) transmission lines is presented that overcomes the RFattenuation to achieve under 0.06Np/cm variation by using a preemphasisfilter with a flat group delay of less than 70ps.
