Novel Fiber Bragg Grating Design
Abstract: We proposed and demonstrated a novel practical fiber Bragg grating (FBG) fabrication setup constructed with high performance linear stages, piezoelectric translation (PZT) stages, and a highly stable continuous wave laser. Fiber Bragg grating (FBG) sensors have emerged as advanced tools for monitoring a wide range of physical parameters in various fields, including structural health, aerospace, biochemical, and environmental applications. These microscopic structures within optical fibers have become the bedrock of cutting-edge sensor.

Measurement of laser diode junction temperature using voltage drop method
The electrical test method (ETM) for diode junction temperature measurements is based on a three-step operation using the test set up shown (left) First, IM is applied and the diode under test (DUT) junction voltage is measured—the measurement value is referred to as. This paper describes and compares three different methods for laser diode junction temperature measurements. For Pulsed Operation, the Effective Thermal Resistance Varies With Time, Making it Difficult to Calculate TJ. The base-emitter voltage (V BE) of a BJT is the voltage drop across the base and emitter of the transistor.
