Artix said:[quote author=heruursciences link=1215835001/20#29 date=1216100710]Case positive is common for high power laser diodes because the emitting stripes are made near the surface of the positive side of the dies, so they mount it that way to avoid heat flowing through the chip and cooking it. Even case negative diodes are usually positive side down, just there is an insulating barrier made of either boron nitride or beryllium oxide- sometimes even DIAMOND!- put between the + side of the diode and the case.
:-/ i don't get it... any pictures?
jamilm9: why would I waste a perfectly good $2.99 to get a piece of low quality metal that looks hideous, when I have a Meredith glass module... The diode deserves more than DX [/quote]
If your cheap like me.
