    • A small high-performance unidirectional optical power monitor having a directional characteristic of 30 dB or higher is provided. A sleeve in which the center axes of round holes in which a GRIN lens and a photo-diode are inserted and fitted are eccentric from each other is used. The entire sleeve or the inner surfaces are formed by a black non-light-transmissive material. The position of the intermediate wall in the sleeve is at a distance of 0.55 L to 0.8 L from a tap film of the GRIN lens. L is the distance between the tap film and the lens extreme end of the photo-diode. Preferably, the angle of the intermediate wall is in the range from 45 to 135 degrees, the light reflectivity of the wall surfaces of the intermediate wall and the inner wails is 10% or less, the surface roughness is 2 nm or higher, and the undulation is ½ or less of the wavelength of light used.
    • 提供具有30dB或更高的方向特性的小型高性能单向光功率监视器。 使用其中插入和装配GRIN透镜和光电二极管的圆孔的中心轴线彼此偏心的套筒。 整个套筒或内表面由黑色非透光材料形成。 中间壁在套筒中的位置距离GRIN透镜的分接膜为0.55L至0.8L的距离。 L是分接膜与光电二极管的透镜最终端之间的距离。 优选地,中间壁的角度在45〜135度的范围内,中间壁和内部壁的壁面的光反射率为10%以下,表面粗糙度为2nm以上, 波动是所使用的光的波长的1/2或更少。
