Constant Temperature Control of Semiconductor Laser Based on Temperature Characteristics of pn Junction LIN Zhi-qi1,2, ZHANG Yang2, LANG Yong-hui2, YIN Fu-chang1 ( 1.

School of Electric and Electronic Engineering, Changchun University of Technology, Changchun 130012, China) Abstract: Since the temperature has a great effect on emission wavelength of semiconductor laser device, constant temperature control is necessary to the situation which require high wavelength stabilization. In view of temperature error in constant temperature control of semiconductor laser by means of temperature sensor, a new method taking pn junction of laser diode (LD) itself as temperature detector to achieve the goal of constant temperature was proposed. The drive circuit of semiconductor refrigerator was designed also. This method makes use of the temperature sensitive characteristic of pn junction to test the temperature of pn junction through its terminal voltage. The experiment results showed that the temperature error caused by temperature gradient is eliminated; the experiment speed is increased; the overshoot value is reduced distinctly; and the static error and fluctuation were also eliminated. Key words: laser diode (LD); temperature detecting; temperature measurement by pn junction; semiconductor refrigeration" } ] } ] } ] }, "response": [], "contributions": [], "acknowledgements": [], "conflict": [], "supportedby": [], "articlemeta": { "clc": [ [ { "name": "text", "data": "TN248.4" } ] ], "dc": [], "citeme": [], "fundinggroup": [], "history": { "received": "2008-09-25", "revised": "1900-01-02", "epub": "2009-04-30", "ppub": "2009-04-30", "opub": "2020-07-02" } }, "appendix": [], "ethics": [], "supplementary": [], "issue": "2", "volume": "30", "originalSource": [] }
