Abstract: A method for determining receiver coupling efficiency includes varying optical power inputted into a half active optical cable to determine a maximum optical power at which the TIA squelches and determining a receiver coupling efficiency by calculating a ratio of a threshold optical power to the maximum optical power at which the TIA squelches. A method of determining link loss in a channel includes varying optical power of a light source to determine the maximum optical power at which the TIA squelches and determining the link loss in the channel by subtracting the maximum optical power from the threshold optical power. A method of determining link topology includes selecting a pattern of optical powers and matching a pattern of squelched and non-squelched outputs with the pattern of optical power. An active optical cable includes memory storing a value related to an initial link loss of the active optical cable.

Abstract: An optical module includes a Silicon Photonics chip that transports a light signal and a coupler chip that includes a waveguide and that is attached to the Silicon Photonics chip so that the light signal is transported along a light path between the Silicon Photonics chip and the coupler chip. The light path in the coupler chip includes a guided section that includes the waveguide that guides the light signal and an unguided section that does not guide the light signal in any other waveguide structure. The cross-sectional size of the beam defined by the light signal is largest at the interface between the Silicon Photonics chip and the coupler chip.
