Title: OPTICAL COMPONENT AND OPTICAL MODULE
Abstract:
An optical component (10) includes an arrayed waveguide grating (1) and an optical element (2). The arrayed waveguide grating comprises a first waveguide (11) including a plurality of waveguides through which a plurality of optical signals having mutually different wavelength bands separately propagates, a second waveguide (15) through which a multiple-wavelength signal composed of a plurality of multiplexed optical signals propagates, and an arrayed waveguide (13) arranged on an optical signal path between a first end (18) of the first waveguide and a first end (28) of the second waveguide, the arrayed waveguide grating having first transmission wavelength characteristics including a plurality of transmittance peaks. The optical element is arranged on an optical signal path connected to a second end (19) of the first waveguide or on an optical signal path (4) connected to a second end (29) of the second waveguide, the optical element having second transmission wavelength characteristics wherein the transmittance has a local minimized value at a wavelength matching the wavelength at the peak of the first transmission wavelength characteristics.
