Abstract
A microprocessor‐controlled feedback system using a linear variable differential transformer to measure the compression of a fiber Bragg grating with a view to improve the tuning accuracy of a fiber grating laser is reported. This technique overcomes the large hysteresis of the PZT actuator normally used to compress the grating. A tuning range of about 20 nm with a readout wavelength accuracy of better than ±0.05 nm was achieved. © 2002 John Wiley & Sons, Inc. Microwave Opt Technol Lett 32: 37–40, 2002.
