    摘要: This application discloses a transmitter optical subassembly, an optical component, an optical module, and a passive optical network system. The transmitter optical subassembly includes a substrate and a direct modulated laser disposed on the substrate. A single-stage isolator, a polarization direction rotator, and an optical branching filter are disposed side by side on the substrate in a light propagation direction. The polarization direction rotator can adjust linearly polarized light to P-polarized light, the optical branching filter includes an optical splitter subassembly and a filter subassembly, and an optical splitter film in the optical splitter subassembly is an optical splitter film with P polarization. The polarization direction rotator adjusts the incident linearly polarized light to the P-polarized light, and the optical splitter film in the optical branching filter is the optical splitter film with P polarization; therefore, all P-polarized light with single polarization can pass through the optical branching filter, without causing any polarization loss or two peaks. In this way, output optical power of the transmitter optical subassembly is increased, and the optical component can better implement a wavelength locking function.
