What's the difference between a rhombus lattice and a hexagonal lattice in photonics?
I am learning photonic crystal slabs. I try to figure out what the difference between a rhombus lattice and a hexagonal lattice in photonics is?
All I know is that they have diffefent Brillouin zones,...

Band theory of Photonic crystals
I have a basic question about the band structure of photonic crystals.
If I have a periodic potential, then Bloch-theory tells me that the bands yield the energy spectrum of the Hamilonian which is ...

Is characteristic temperature $T_0$ of a semiconductor laser geometry independent?
Can I compare $T_0$ of one laser to another one, with different length and width?
For example, let's say there are two lasers:
Laser A
Width: 20 $\mu m$
Length: 500 $\mu m$
$T_0$: X
Laser B
Width: ...

Solid-state lasers: The peak power of each pulse is at least three orders of magnitude above the average output power?
My textbook, Solid-State Laser Engineering, 6th edition, by Walter Koechner, says the following:
Average Output Power. The majority of solid-state lasers available commercially have output powers ...

Non-monochromatic (multi-wavelength?) lasers
I was recently doing some reading on lasers, and I came across the fact that truly monochromatic light is impossible, which then obviously implies that truly monochromatic lasers are impossible. But ...

What is the difference between non-local optical response and local optical response?
Does anyone knows what is the difference between non-local optical response and local optical response in metal-dielectric-metal?
