Abstract(s)
We introduce and report recent developments on a novel five port
optoelectronic voltage controlled oscillato
r consisting of a resonant tunneling
diode (RTD) optical-waveguide integrated with a laser diode. The RTD-based
optoelectronic oscillator (OEO) has both optical and electrical input and output
ports, with the fifth port allowing volta
ge control. The RTD-OEO locks to ref-
erence radio-frequency (RF) sources by either optical or electrical injection
locking techniques allowing remote sync
hronization, eliminating the need of
impedance matching between traditional RF oscillators. RTD-OEO functions
include generation, amplification and distribution of RF carriers, clock recov-
ery, carrier recovery, modulation and demodulation and frequency synthesis.
Self-injection locking operation modes, where small portions of the output elec-
trical/optical signals are fed back into the electrical/optical input ports, are also
proposed. The self-phase locked loop configuration can give rise to low-noise
high-stable oscillations, not limited by
the RF source performance and with no
need of external optoelectronic conversion.
