λHomework Statement
A symmetric confocal resonator with mirror spacing d =16 cm, mirror reflectances 0.995, and n = 1 is used in a laser operating at λ[o] = 1 μm.
(a) Find the radii of curvature of the mirrors.
(b) Find the waist of the (0,0) (Gaussian) mode.
(c) Sketch the intensity...
Homework Statement
A beam of light is composed of a mixture of unpolarized and linearly polarized waves. The beam is analyzed with a polarizer. As the transmission axis is rotated, the transmitted irradiance varies from a maximum I[max] to a minimum of 1/3 I[max]. What is the ratio of the...
Homework Statement
A Light emitting diode (LED) drives a single mode waveguide that is 10 km long, and has a material dispersion of – 100 ps/km/nm for wavelengths near 800 nm. The LED radiation has a spectral width of 60 nm and is centered at 800 nm.
a) If the LED is pulsed on and off in 5...
