Beam Profile Characterisation of an Optoelectronic Silicon Lens-Integrated PIN-PD Emitter between 100 GHz and 1 THz
نویسندگان
چکیده
Knowledge of the beam profiles terahertz emitters is required for design instruments and applications, in particular designing communications links. We report measurements an optoelectronic silicon lens-integrated PIN-PD emitter at frequencies between 100 GHz 1 THz observe significant deviations from a Gaussian profile. The were found to differ H-plane E-plane, vary strongly with emitted frequency. Skewed irregular side-lobes observed. Metrological aspects profile are discussed addressed.

Surface and Volumetric Backscattering Between 100 GHz and 1.6 THz
Successful development of remote sensing and communication systems in the terahertz band requires a better understanding of the scattering behavior of various structures. Materials that could be considered homogeneous and smooth at microwave frequencies may begin to display surface and volumetric scattering behavior in the terahertz band. The co-polarization backscattering coefficient of severa...
متن کاملOptoelectronic time-domain characterization of a 100 GHz sampling oscilloscope
We have performed an optoelectronic measurement of the impulse response of an ultrafast sampling oscilloscope with a nominal bandwidth of 100 GHz within a time window of approximately 100 ps. Our experimental technique also considers frequency components above the cut-off frequency of higher-order modes of the 1.0 mm coaxial line, which is shown to be important for the specification of the impu...
متن کاملThin film PIN photodiodes for optoelectronic silicon on sapphire CMOS
In this paper, we consider both the utility of SOS substrates as a vehicle for optoelectronic packaging and the high speed silicon photodiodes available on a commercial SOS process. We show optical responses for six configurations of PIN photodiodes designed in this process. Our results indicate that photodiodes native to this process will operate at better than gigabit rates and produce signal...

متن کاملAntenna Enhanced Graphene THz Emitter and Detector.
Recent intense electrical and optical studies of graphene have pushed the material to the forefront of optoelectronic research. Of particular interest is the few terahertz (THz) frequency regime where efficient light sources and highly sensitive detectors are very challenging to make. Here we present THz sources and detectors made with graphene field effect transistors (GFETs) enhanced by a dou...
