Dependent claims

A micro integratable tunable laser assembly (m-ITLA), characterized in that the m-ITLA comprises:

an electrical interface for interfacing with a host;
a tunable laser module for irradiating a laser light;
a control unit, for at least controlling the tunable laser module according to information received from the host via the electrical interface;
a dual-sided printed circuit board (PCB) defining first openings, wherein each of the electrical interface, the tunable laser module, and the control unit is mounted onto either side of the PCB;
a first plate defining first projections;
a second plate defining second projections;
and
a pad provided between the tunable laser module and at least a portion of the first and second plates, the pad being adaptable to be compressed,
wherein the first openings are corresponding to the respective first projections and the respective second projections,
wherein the PCB is adaptable to be retained between the first and second plates by the first and second projections when the first and second plates are secured to each other,
wherein the pad is adaptable to hold the tunable laser module and/or to dissipate heat from the tunable laser module, and
wherein the m-ITLA has a length of about 37 mm or less and a width of about 20 mm or less.

#Embodiments of the present disclosure will be described in detail below with reference to the drawings. Note that similar reference numerals are used to refer to similar elements throughout the drawings, and thus repetitive descriptions thereof are omitted.

#FIG. 1 is a block view schematically illustrating an embodiment of a micro integratable tunable laser assembly 100 according to an embodiment of the present disclosure.

#The m-ITLA 100 may include an electrical interface 101 for interfacing with, for example, a host (not shown) external to the m-ITLA 100. In a preferred embodiment, the interface 101 can be implemented as, for example, RJ232 interface, Serial Peripheral Interface (SPI), or I2C-Bus, which are well known in the art. With the interface 101, incoming information can be received from the host to the m-ITLA 100, and outgoing information can be transmitted from the m-ITLA 100 to the host.
