Title:
COMPACT OPTICAL FIBER AMPLIFIER
Document Type and Number:
Japanese Patent JP2019021909
Kind Code:
A
Abstract:
To provide an optical fiber coil supporting structure in which an amplifying fiber portion of an optical amplifier is miniaturized.SOLUTION: A fiber-based optical amplifier is assembled in a compact configuration by utilizing a flexible substrate to support an amplifying fiber as flat coils that are "spun" onto the substrate. A supporting structure for the amplifying fiber 20 is configured to define the minimal acceptable bend radius for the fiber, as well as the maximum diameter that fits within the overall dimensions of an amplifier package. Pressure-sensitive adhesive coating is applied to the flexible substrate 30 to hold the fiber in place. By using flexible material with an acceptable insulating quality (such as a polyimide), further compactness in a final assembly is achieved by locating electronic components in a space underneath a fiber enclosure.SELECTED DRAWING: Figure 2
