Product Code : SCL-EELE-13239
Indian Lab Suppliers supplies the Construction and Study of Mode Properties of Planar Waveguide (Product ID: 13239) as part of its electronics engineering lab equipment range. It is a laboratory set-up for making single-mode and multimode planar glass waveguides by ion exchange and measuring their mode properties with a laser and prism coupler.
Quick Answer
Waveguides are formed by potassium ion exchange: soda-lime glass substrates are held in a molten potassium nitrate (KNO3) bath in a temperature-controlled ceramic furnace, and the exchange time sets the guide depth. Light from a 1 mW red laser on an optical rail bench passes a 10× Galilean collimator and a polarizer, then enters the guide through a high-index right-angle prism held in a prism-coupler mount on graduated rotation stages with Y and Z translation. A laser power meter records the mode spectrum for TE and TM polarisation, from which students calculate mode effective indices, guide index and thickness, and single-mode design limits for step-index and graded-index guides. A quartz half-cylinder lens adds reflection, refraction, critical angle and Brewster angle experiments. A He-Ne laser and a 635 nm laser are both named for this set-up; please confirm the laser type at quotation. Wear gloves and eye protection with the hot salt bath and furnace, and never look into the laser beam.
