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.
