title: Temperature dependence of bend- and twist-induced birefringence in a low-birefringence fiber.
abstract: The temperature dependence of the bend- and twist-induced birefringence in LB600 low-birefringence fiber has been measured at lambda = 0.633 microm. The relative temperature dependence B = (1/beta)dbeta/dT of the bend-induced birefringence beta was found to be (5.7 +/- 0.2) x 10(-4) K(-1) over a temperature range from -5 to 70 degrees C. The relative temperature dependence A = (1/g)dg/dT of the twist-induced birefringence g was found to be (4.95 +/- 0.25) x 10(-4) K(-1) (between 22 and 150 degrees C). The measured values of A and B are in accordance with a relative temperature dependence (1/C)dC/dT of the stress-optic coefficient C equal to (4.2 +/- 0.2) x 10(-4) K(-1).
