位相周波数検出器(PFD)とFALC 110から構成されたDFCロッキングエレクトロニクスは光周波数コムアプリケーションに対して優れた位相周波数ロッキング機能を提供します。PFDのRF信号入力はDFC MDのRF出力信号で使用するように設計されています。PFDによって生成されたエラー信号はFALC 110レギュレータの入力用に供給されます。 FALCのメイン出力はPFDを通過して半導体レーザー電流を変調する高速フィードバック回路のリモートスイッチングを可能にします。エラー信号のコピー(mon.out)はDL pro半導体レーザー走査用ピエゾ素子 (Fine In) とDLC pro半導体レーザーコントローラの全てのデジタルPID上でスローなフィードバックループ閉回路を構成するために使用されます。DFC UIソフトウェア(TOPAS DFC)上のボタン操作により低速および高速のフィードバックループを有効または無効にすることができます。

Applications
The DFC locking electronics consisting of the Phase Frequency Detector (PFD) and FALC 110 provides high-end phase frequency locking for comb applications. The PFD RF input is designed for use with the RF output signal of the DFC MD. The error signal generated by the PFD is fed to the input of the FALC 110 regulator. The main output of the FALC is passed through the PFD to allow for remote switching of the fast feedback loop which modulates the laser diode current. A copy of the error signal (mon. out) is used to close the slow feedback loop acting on the DL pro piezo (Fine In) with the all-digital PID of the DLC pro. Slow and fast feedback loop can be enabled and disabled with a push of a button in the DFC user interface (TOPAS DFC).
