Concept
Free Spectral Range
Free spectral range
(FSR) is the
frequency interval
between
successive resonant modes
in a resonator, such as an
optical cavity
or a
Fabry-Pérot interferometer
. It determines the
spacing of transmission peaks
and is inversely related to the
round-trip time of light
within the resonator, playing a crucial role in
applications like wavelength filtering
and
mode-locked lasers
.

Optical Cavity
An
optical cavity
is a
set of mirrors
that forms a
closed path for light
, allowing it to
bounce back and forth
to
enhance its intensity
and coherence. This setup is crucial in
devices like lasers
and interferometers, where
controlled light amplification
and
precise measurement
are essential.

. It consists of two
parallel reflective surfaces
that create
multiple reflections
, enhancing the
resolution of spectral lines
in
applications like spectroscopy
and telecommunications.
Concept
Resonant Modes
Resonant modes
refer to the
specific frequencies
at which a
system naturally oscillates
with
greater amplitude
due to
constructive interference
. These modes are fundamental in understanding
phenomena in acoustics
, optics, and
mechanical systems
, where they determine the behavior and efficiency of
wave propagation
and
energy transfer
.
Concept
Transmission Peaks
Transmission peaks
refer to the points at which the transmission of a signal, wave, or data reaches its
maximum efficiency
or amplitude. Understanding these peaks is crucial for
optimizing communication systems
, minimizing losses, and enhancing the overall performance of
transmission networks
.
Concept
Round-trip Time
Round-trip time
(RTT) is the
duration it takes for a signal to travel
from the
source to a destination
and back again, crucial for assessing
network performance
and latency. Understanding RTT is essential for
optimizing data transmission efficiency
, as it directly impacts the speed and
reliability of communication networks

Concept
Mode-locked Lasers
Mode-locked lasers
generate
ultra-short pulses of light
by
synchronizing the phases
of
different frequency modes
