New Multi-Axis Alignment System for Silicon Photonics


Auburn, MA – PI’s household of photonics alignment automation programs has expanded with a brand new air-bearing-based multi-axis meeting and an EtherCat-based high-performance movement controller with embedded alignment algorithms. The distinctive mixture of direct-drive maintenance-free air bearing alignment phases with refined first mild search and alignment routines end in extraordinary time financial savings – a essential think about silicon photonics alignment automation.

​​​​​​How the Alignment System Works

The F-143 alignment system relies on three A-143 air bearing phases in an XYZ configuration. Every axis offers a journey vary of 25mm, with a most velocity of 250mm/sec, and acceleration as much as 10m/s2. Preloaded air bearings assure distinctive flatness and straightness of 0.25µm and 0.05µm, respectively. The vertical axis stage is supplied with an adjustable counterbalance and brake mechanism to offset the power of gravity on the motor and stop potential collisions with a SiPh wafer within the occasion of an influence failure.

A particular, EhterCat-based movement controller with embedded photonics alignment algorithms and user-friendly software program permits the system to carry out alignments as much as 100 occasions sooner than standard optical alignment engines.

Put on-Free and Clear-Room Appropriate

The usage of friction-free, wear-free, and maintenance-free parts together with the absence of lubricants makes the air bearing automated alignment system ideally suited to silicon photonics waver probing and different clean-room purposes.

Absolute Encoder Choice

A key characteristic of those phases is the selection of encoders, together with absolute and incremental choices. Absolute encoders present specific place data, facilitating exact willpower of every angular place with out the necessity for incremental counting. This characteristic ensures instant availability of place data upon power-up, enhancing operational effectivity and security.
