| Summary: | 碩士 === 國立交通大學 === 光電(科學)研究所 === 83 === In this thesis, we have developed a comb-like wide bandwidth
electrical signal source on an optical carrier. This is based
on an integrated electrooptic modulator (IOM) which serves
as an electro-optic harmonic mixer and its nonlinear
characteris- tics is utilized for measuring the bandwidth of a
photodetector. The bandwidth of this technology can be higher
than for the bandwidth of the IOM.It is successily demonstrated
a photo- detector with a bandwidth of about 3GHz .We estimate
the bandwidth of this technique will exceed 100 GHz if we have
an IOM for which the half-wave voltage is less than 3 Volt
and bandwidth is 5 GHz.Moreover,a comparsion of several
different methods for measuring the bandwidth of photodetector
is presented and analyzed.
