Optical magnetic field (current) sensors have recently reached practical application. This paper reports on evaluations of LPE garnet (TbY) IG crystals for magnetic field sensors, and on their optical characteristics. 100 ¿m thick films were produced on {111} GGG substrate, but pits appeared even when using a Pb<inf>o</inf>/B<inf>2</inf>O<inf>3</inf> melt(More)
This paper reports on fabrication of an LD (laser diode) module with an optical isolator using YIG crystals in which the optical parts are fixed by soldering and YAG laser welding. The LD to single-mode fiber coupling efficiency was less than -4.6 dB, and the isolator insertion loss was 0.1 dB. Output variation in the 0 to 50&#x000B0;C temperature range was(More)
