Using photonics in communitcation, the data can be transferred with
10 times faster
1000 times faster
1 million times faster
lower speed than usual
They symbol (δ) stands for?
density of states
detuning or decoupling
data transfer
The data signal can be transmitted using SPs in a waveguide for
infinite length
50 nm
100 micron
Light can be confined, focused and guided into waveguides using
nanoscale gold dots
dielectric nanoparticles
nanodimension optical fibers
practically impossible
collective excitation of (a) in metals known as plasmonics
What does the symbol Γpl represent?
A gamma radiation
density of plasmons
spontaneous emission rate of plasmons
For the single photon transistor in addition to the ground state and excited state we need a (a) state for spin flipping.
When the radius of a nanowire (R) is reduced down to R << λ0, (λ0 -> the wavelethength of light) the nanowire
exhibits good confinement
becomes opaque
gets detuned from the optical trail of photons
The single photon transistor gets the name because
it has a channel width of allowing only a single photon
the single captured photon decides the device is switched ON or OFF
it can process only a single photon at a time
The time reversal process in single photon transistor drives the emitter from
|s> state to |g> state
|s> state to |e> state
|e> state to vacuum
How do you feel about the quizizz experince?
Better than others
Moderate
Same as other quiz platforms
Its awkward
