8.2-7 Single-Mode Waveguide. What is the largest thickness d of a planar symmetric dielectric
waveguide with refractive indexes n1 = 1.50 and n2 = 1.46 for which there is only one TE
mode at A, = 1.3 µm? What is the number of modes if a waveguide with this thickness is
used at A, = 0.85 µm instead?

Suppose you measured a spectrum of a laser source which peaks at a wavelength of 810 nm. Find the energy (in eV) associated with this wavelength. From the LED spectrum data you want to find the width of the peak at half the height of the peak. The wavelengths at which the intensity is half of its peak value are 630 nm and 666 nm respectively. Using these wavelengths determine the width of the peak in units of energy (eV). From the N2 spectrum data you noted two prominent peaks at wavelengths 330 nm and 350 nm. Determine the energy associated with each peak. The larger energy represents the energy difference between the vibrational ground states of two molecular orbitals (denoted by C’IIu and B³IIL). The smaller one represents the energy difference between the vibrational ground state of the C'II, orbital and first excited vibrational state of B³II.. The difference between these energies represents the energy difference between the ground and first excited vibrational levels. Find this…

Electromagnetic Plane Waves: In infrared optical systems germanium is often used to form optical components. For infrared wavelengths, germanium can be considered lossless, non-magnetic (u- 1) and has a relative dielectric constant e 16. Consider a plane wave inside a piece of germanium incident at the interface between germanium and air. The plane wave is polarized parallel to the plane of incidence and the angle of incidence is halfway between the Brewster angle and the critical angle for total internal reflection. Germanium: Air: H1 = Ho i E1 = 16e, H2 = Ho i €2 = €o %3. Be A, a) What is the angle of incidence? b) What are the reflection and transmission coefficients for the wave at this angle of incidence?
