[0044] POET can be used to construct a variety of high performance transistor devices, such as complementary NHFET and PHFET unipolar devices as well as n-type and p-type HBT bipolar devices. POET can also be used to construct a variety of optoelectronic devices which include:
- a thyristor VCSEL laser;
- an NHFET laser;
- an PHFET laser;
- a thyristor optical detector;
- an NHFET optical detector;
- a PHFET optical detector;
- a semiconductor optical amplifier (SOA) or a linear optical amplifier (LOA) based on either one (or both) of the n-type and p-type quantum well interfaces;
- an absorption (intensity) optical modulators based on either one (or both) of the n-type and p-type quantum well interfaces;
- a phase modulator based on either one (or both) of the n-type and p-type quantum well interfaces;
- a waveguide switch; and
- a passive waveguide.
