Answer #1

Assume an air-filled Fabry-Perot interferometer made from two
similar, parallel mirrors. For a wavelength of 610nm, the fraction
of transmitted light to incident light is 0.0154. The distance of
separation is ℓ = 2.60μm. What is (a) the finesse, F, and (b) the
reflectance of the mirrors, R, when assuming only reflective
contributions to the etalon's finesse?

The manual of Fabry-Perot interferometer references the value of
finesse F equal to 360. The thickness of air gap between mirrors is
insured by the glass spacer is 10 um. Calculate the amplitude
reflection coefficient r provided by one mirror.

For a Fabry-Perot interferometer, suppose that two close
wavelengths λ and λ + ∆λ are just resolved. Argue that the
resolving power λ/∆λ is equal to −δ/∆δ, and hence show that the
resolving power is R = mF.

1. A Fabry-Perot etalon (or resonator) is formed by two mirrors
in air. The distance between mirrors is 1.25 (mm), and the
reflectance of each mirror is 0.92.
What is the mode of the etalon that is closest to the wavelength
of 1.55 (µm)?
2. What is the separation of the modes in the etalon?
3. The finesse, F, of the etalon is defined as the
ratio of mode separation to spectral width of each mode, and
depends on the...

???ALASKA AIRLINES: NAVIGATING CHANGE
In the autumn of 2007, Alaska Airlines executives adjourned at
the end of a long and stressful day in the
midst of a multi-day strategic planning session. Most headed
outside to relax, unwind and enjoy a bonfire
on the shore of Semiahmoo Spit, outside the meeting venue in
Blaine, a seaport town in northwest
Washington state.
Meanwhile, several members of...
