In a package of a phosphor converted white LED (blue LED + Yellow phosphor), two heat generation mechanisms exist.
1. Joule heating at junction temperature of blue LED
2. Heat generation of the yellow phosphor layer due to stokes shift and blue light absorption.
Now I have questions.
1. Where...
polarized light and refraction!
Hi guys
I need to discuss the polarized light in the waveguide and its refraction at an interface between two different media.
if the light is polarized like in the picture(see attached) and oscillating only up and down (linear polarization), then does the...
hello
I have a question.
If 10V and 100mA is injected to GaAs laser ridge size is 1mm(length), 10um(width), 5um(thickness), which temperature can be generated in the ridge?
the ridge is covered by gold for the electrical contact.
Is it possible to calculate?
I tryed to serch the...
