A slope gain equalizer that corrects a slope of a gain characteristic of an optical signal in a predetermined wavelength bandwidth. An interference filter, which allows insertion losses in a predetermined wavelength region to be inclined in opposite directions between a transmitting direction and a reflecting direction from a short wavelength side to a long wavelength side, is arranged between a dual-core fiber collimator and a single-core fiber collimator facing each other on an optical axis. An optical signal of a predetermined bandwidth inputted from a first or second optical fiber held by the dual-core fiber collimator is reflected by the interference filter and outputted from the second or the first optical fiber. An optical signal inputted from a third optical fiber held by the first optical fiber or the single-core fiber collimator is transmitted through the interference filter and outputted from the third or the first optical fiber.

Slope gain equalizer

An interference filter module comprises two optical fiber collimators arranged on an optical axis so as to be opposed to each other, interference filters, and a casing including a main body portion and filter holding portions to be mounted into the main body portion, which are configured to hold the interference filters. Two interference filters including a kth filter when counted from a front end and a k-th filter when counted from a rear end are determined as a k-th set. The two interference filters of the k-th set are accommodated in two filter holding portions, each of which is a k-th holding portion when counted from the front end and the rear end, respectively. The two filter holding portions have rotation axes in directions orthogonal to a fore-and-aft direction and are rotatably held by the casing. The rotation axes of the filter holding portions are orthogonal to each other.

A heat exchanger includes a flat tube and a plurality of fins. The plurality of fins are arranged on the flat tube and inclined with respect to a longitudinal direction of a cross section perpendicular to an axis of the flat tube. The plurality of fins may be inclined at different angles with respect to the axis of the flat tube. The flat tube may include a straight portion on which the plurality of fins are arranged, and a bend on which at least one fin other than the plurality of fins is arranged. The at least one fin extends perpendicularly to the axis of the flat tube.

In a wavelength selective filter, an optical fiber collimator, an interference filter, and a reflective plate are arranged in this order from front to rear along a z-axis. The collimator has a collimator lens disposed on the rear side of an optical fiber that is opened. The interference filter includes light incident and emitting surfaces, opposed with their xy-planes rotated about a y-axis at a predetermined rotation angle. The reflective plate has a front reflective surface having a normal direction along a z-axis direction, and reflects, toward the front, light incident from the front through the interference filter, to be incident onto the interference filter. The optical fiber collimator causes the input light propagating through the optical fiber from the front to be incident onto the interference filter, and converges the reflected light transmitted through the interference filter to the optical fiber and outputs the light.
