Fibre Only Coupling
Suited to simple Si-PICs that do not have any integrated electrical components. Allows users to perform ﬂexible electrical probe-tests on a stable optical platform.
Two Single Fibres (FOC-2S)
Available with either SM- or PM ﬁbres, and terminated in FC-APC connectors. Light-path with a loss of less than -20dB is needed across the PIC, or it will be impossible to package the PIC.
Allows multiple user ﬁbre-channels to be coupled to the Si-PIC. Uses an optical-shunt between the ﬁrst and last couplers on the PIC-side grating array. There are options for either 8 or 14 user-channels on the PIC (corresponding to 10 and 16 channel ﬁbre arrays with optical-shunt alignment). Users may also choose a 250µm or 127µm pitch on the grating-array, and SMF or PMF ﬁbres (both terminated in FC/APC connectors).
Symmetric application of 2x one-ﬁbre-array FOCs. Both ﬁbre arrays are independently aligned using separate optical-shunts. In principle, a user may specify different ﬁbre types, user-channels, ﬁbre-pitch for both arrays, but paired arrays are the most common conﬁguration, and the pricing matrix here is for paired arrays. Again, SMF and PMF ﬁbre-arrays are terminated in FC-APC connectors.
Fully packaged modules (FPMs)
This offers ﬁbre- and optical- connectivity, as well as thermal stability. They are based on the Tyndall-PCB module described in Section 2.6 of the guide notes, and offer users a low-cost “off the shelf” solution to a fully packaged device for demonstrations and prototyping. FPMs allow for up to 20 DC connections to the Si-PIC and a range of single-ﬁbre and ﬁbre-array QPC options. The integrated thermistor and TEC ensures thermal stability of the PIC, when connected to an external PID controller (not supplied with the module).
Two Single Fibres Option (FPM-2S)
Available with either SM- or PM-ﬁbres, and terminated in FC-APC connectors. Up to 10 DC wire-bond connections can be made to the two opposite sides of the Si-PIC. A 10kOhm thermistor is integrated in the Tyndall-PCB and a 3W TEC transfers heat from the PIC into the aluminium-body of the module.
One Fibre-Array Option (FPM-1A)
Allows multiple user ﬁbre-channels to be coupled to the Si-PIC. As well as two sets of 10 DC wire-bond connections, and thermal management. There are options for either 8 or 14 user channels on the PIC (corresponding to 10 and 16 channel ﬁbre-arrays with optical-shunt alignment). Users may also choose between a grating-array pitch of 250µm or 127µm, and SMF or PMF ﬁbres. Both the SMF and PMF ﬁbre-arrays are in FC/APC connectors. Thermal management is provided by the integrated thermistor in the Tyndall-PCB and the 3W TEC, which couples heat from the PIC into the mechanical body of the module, for heat-sinking to the ambient.
Two Fibre-Arrays Option (FPM-2A)
Allows for twice the optical connections of the FPM-1A option. As well as two sets of 10 DC wire-bond connections, and thermal management. Users can choose between a pair of ﬁbre arrays offering 2 x 8 or 2 x 14 user-channels on the PIC (corresponding to pairs of 10 and 16 channel ﬁbre arrays with optical-shunt alignment). Users may also choose between a grating-array pitch of 250µm or 127µm, and SMF or PMF ﬁbres. Both the SMF and PMF ﬁbre-arrays are in FC/APC connectors.
