14-pin Butterfly Package
The 14-pin Butterfly Package is a compact industry standard housing for optoelectronic modules, with options for hermetic sealing. It provides a fiber feed-through, electrical fan-out, and built-in thermal management for photonic integrated circuits (PICs). PHIX provides design guidelines that promote standardization and accelerate module design, enabling reduced packaging costs and lead times.
Key features
- PICs of various sizes and several material platforms are supported.
- Edge or grating coupled SM or PM fiber array of up to 8 channels.
- 14 pins of DC connections.
- Integrated thermoelectric cooler (TEC) and thermistor for thermal control.
- Options for full or semi-hermetic sealing.
- Suitable for MIL-STD-883 and Telcordia quality standards

Example application: external cavity tunable laser
The 14-pin butterfly package is a popular housing for external cavity tunable lasers, for which PHIX developed standardized production processes suitable for high-volume manufacturing. The typical building blocks for these devices are shown here.
Design guidelines documentation
To enable cost-effective packaging with short lead times for the 14-pin Butterfly Package, PHIX offers design guidelines for your chip and its surrounding architecture. We also supply a STEP-file that indicates the available design area within the housing. Conformity with these guidelines allows PHIX to make use of standardized (and automated) production processes and off-the-shelf building blocks. The design guidelines for the 14-pin Butterfly Package build on the PIC Design Guidelines document that describes good design practices for all package types. We highly recommend that you download and study both documents.
