Abstract:

An wave division multiplexed (WDM) optical transmitter is disclosed including a directly modulated laser array and a planar lightwave chip (PLC) having a plurality of OSRs that receive outputs of the laser array and increase the extinction ratio of the received light. An optical multiplexer receives the outputs of the OSRs and couples them to a single output port. The multiplexer has transmission peaks through its ports each having a 0. 5 dB bandwidth including the frequency of a laser in the array. The optical multiplexer may be embodied as cascaded Mach-Zehnder interferometers or ring resonators.

Abstract:

Multi-laser transmitter optical subassemblies (TOSAs) for optoelectronic modules. In one example embodiment, a multi-laser TOSA includes first and second lasers configured to generate first and second optical signals, respectively, a polarization beam combiner (PBC), first and second collimating lenses positioned between the first and second lasers, respectively, and the PBC, a half waveplate positioned between the first laser and the PBC, and a focusing lens. The half waveplate is configured to rotate the polarization of the first optical signal. The PBC is configured to combine the first and second optical signals and transmit the combined first and second optical signals toward the focusing lens.

Abstract:

Optical triplexers are disclosed. The optical triplexers include an optical fiber, a first ball lens optically coupling a first optical signal between a first opto-electronic device and a first wavelength selective filter, and a second ball lens optically coupling a second optical signal between a second opto-electronic device and the first wavelength selective filter. The optical triplexers further include a second wavelength selective filter optically coupling the first and second optical signals between the first wavelength selective filter and a third ball lens and a fourth ball lens optically coupling a third optical signal between a third optical signal between a third opto-electronic device and the second frequency selective filter. The second wavelength selective filter optical couples the third optical signal between the fourth ball lens and the third ball lens. Thus, each of the optical signals are selectively coupled between one of the opto-electronic devices and the optical fiber.

Abstract:

Multi-laser transmitter optical subassembly (TOSA). In one example embodiment, a method of fabricating a multi-laser TOSA includes various acts. First, first and second optical signals are transmitted from first and second lasers, respectively. Next, the angle of a first collimating lens is actively adjusted to cause the second optical signal to be aligned with the first optical signal as the first optical signal passes through a first filter and as the second optical signal is reflected by the first filter such that the first and second optical signals are aligned and combined.

The first DLI includes a first left input, a first right input, and a first output and has a free spectral range (FSR) that is about four times a nominal channel spacing. The second DLI includes a second left input, a second right input, and a second output and has an FSR that is about four times the nominal channel spacing. The second stage is coupled to the first stage and includes a third DLI. The third DLI includes a third left input optically coupled to the first output, a third right input optically coupled to the second output, and a third output. An FSR of the third DLI is about two times the nominal channel spacing.
