    • PURPOSE:To reduce the cost of a light guide and to obtain the light guide having an optional shape and optional refractive index distribution by changing the voltage to be impressed in the stage of epitaxial growth with time and forming an electrode into a stripe or opposed comb. shape. CONSTITUTION:Platinum is formed by electron beam vapor deposition over the entire one surface of a Gd3Ga5O12 substrate 2 to constitute the electrode 1 in order to form a two-dimensional light guide. The substrate 2 provided with the electrode 1 is inserted into a soln. 4 and is subjected to epitaxial growth. The voltage is impressed to a platinum crucible 3 side as a positive electrode and the electrode 1 side as a negative electrode from a device 5 right after the start of the growth. The voltage is successively increased according to the function conforming to the desired refractive index distribution. Since the Ga in the soln. is positive ion, the Ga is attracted to toward the negative electrode, by which the quantity to be taken into the grown crystal is increased; namely, the coefft. of effective segregation is increased. The change rate thereof is controllable by the magnitude of the impressed voltage. The change in the impressed voltage with time is converted to a change in the content of the Ga in the thickness direction of the grown crystal, by which the refractive index is decreased in the thickness direction. The graded index type two-dimensional light guide 6 is thus realized.
    • 目的:为了降低光导的成本,并通过随时间改变在外延生长阶段中施加的电压,并且将电极形成为条状或相对的梳子,获得具有任选形状和可选的折射率分布的光导 。 形状。 构成:为了形成二维导光体,在Gd3Ga5O12基板2的整个表面上通过电子束气相沉积形成铂以构成电极1。 设置有电极1的基板2插入到溶胶中。 并进行外延生长。 在开始生长之后,将电压施加到作为正极的铂坩埚3侧和来自器件5的电极1侧作为负极。 根据符合所需折射率分布的功能,电压依次增加。 自从Ga在soln。 是正离子,Ga被吸引到负极,通过该负极,待进入生长晶体的量增加; 即系统。 的有效隔离增加。 其变化率由外加电压的大小控制。 随着时间的推移电压的变化被转换为生长晶体的厚度方向的Ga含量的变化,由此折射率在厚度方向上减小。 从而实现了分级折射率二维光导6。
